Exynos7 devicetree bindings require more input clocks for TOP0 and
PERIC1 clock controllers, than already provided. Existing DTS was not
matching the bindings, so let's update the DTS, even though the error
could be in the bindings.

Exynos5260 bindings require to feed clock controllers with certain clock
inputs. The IO clocks are expected to be provided by the board. The
PHY clocks are usually followed by mux which can choose between the PHY
clock and main 24 MHz oscillator, so skip defining them and just use the
latter one.

-Optional properties:
- - power-domains: a phandle to respective power domain node as described by
- generic PM domain bindings (see power/power_domain.txt for more
- information).
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5433.h header and can be used in device
-tree sources.
-

The UFS for Exynos7 SoC clock controller requires additional input
clocks for the FSYS1 clock controller. Update the bindings to reflect
this, at least in theory. In practice, these input clocks are ignored,
so it is rather adjusting of bindings to existing DTS, without affecting
any real users. I understand that is not how it should be done,
though...

-* Samsung Exynos5260 Clock Controller
-
-Exynos5260 has 13 clock controllers which are instantiated
-independently from the device-tree. These clock controllers
-generate and supply clocks to various hardware blocks within
-the SoC.
-
-Each clock is assigned an identifier and client nodes can use
-this identifier to specify the clock which they consume. All
-available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5260-clk.h header and can be used in
-device tree sources.

-There are several clocks that are generated outside the SoC. It
-is expected that they are defined using standard clock bindings
-with following clock-output-names:
-
- - "fin_pll" - PLL input clock from XXTI

-the hardware blocks. These clocks are defined as fixed clocks in the
-driver with following names:

- - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3

-* Samsung Exynos5260 Clock Controller
-
-Exynos5260 has 13 clock controllers which are instantiated
-independently from the device-tree. These clock controllers
-generate and supply clocks to various hardware blocks within
-the SoC.
-
-Each clock is assigned an identifier and client nodes can use
-this identifier to specify the clock which they consume. All
-available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5260-clk.h header and can be used in
-device tree sources.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It
-is expected that they are defined using standard clock bindings
-with following clock-output-names:
-
- - "fin_pll" - PLL input clock from XXTI
- - "xrtcxti" - input clock from XRTCXTI
- - "ioclk_pcm_extclk" - pcm external operation clock
- - "ioclk_spdif_extclk" - spdif external operation clock
- - "ioclk_i2s_cdclk" - i2s0 codec clock
-
-Phy clocks:
-
-There are several clocks which are generated by specific PHYs.
-These clocks are fed into the clock controller and then routed to
-the hardware blocks. These clocks are defined as fixed clocks in the
-driver with following names:
-
- - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
- - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
- - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
- - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
- - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
- - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
- - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
- - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
- - "phyclk_dptx_phy_clk_div2"
- - "phyclk_mipi_dphy_4l_m_rxclkesc0"
- - "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
- - "phyclk_usbhost20_phy_freeclk"
- - "phyclk_usbhost20_phy_clk48mohci"
- - "phyclk_usbdrd30_udrd30_pipe_pclk"
- - "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
-

+ These clocks are defined as fixed clocks in the driver with following names::

-* Samsung Exynos5410 Clock Controller
-
-The Exynos5410 clock controller generates and supplies clock to various
-controllers within the Exynos5410 SoC.
-
-Required Properties:
-
-- compatible: should be "samsung,exynos5410-clock"
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-- clocks: should contain an entry specifying the root clock from external
- oscillator supplied through XXTI or XusbXTI pin. This clock should be
- defined using standard clock bindings with "fin_pll" clock-output-name.
- That clock is being passed internally to the 9 PLLs.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5410.h header and can be used in device
-tree sources.
-
-Example 1: An example of a clock controller node is listed below.
-
- fin_pll: xxti {
- compatible = "fixed-clock";
- clock-frequency = <24000000>;
- clock-output-names = "fin_pll";
- #clock-cells = <0>;
- };
-
- clock: clock-controller@10010000 {
- compatible = "samsung,exynos5410-clock";
- reg = <0x10010000 0x30000>;
- #clock-cells = <1>;
- clocks = <&fin_pll>;
- };
-
-Example 2: UART controller node that consumes the clock generated by the clock
- controller. Refer to the standard clock bindings for information
- about 'clocks' and 'clock-names' property.
-
- serial@12c20000 {
- compatible = "samsung,exynos4210-uart";
- reg = <0x12C00000 0x100>;
- interrupts = <0 51 0>;
- clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
- clock-names = "uart", "clk_uart_baud0";

-* Samsung Exynos5410 Clock Controller
-
-The Exynos5410 clock controller generates and supplies clock to various
-controllers within the Exynos5410 SoC.
-
-Required Properties:
-
-- compatible: should be "samsung,exynos5410-clock"
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-- clocks: should contain an entry specifying the root clock from external
- oscillator supplied through XXTI or XusbXTI pin. This clock should be
- defined using standard clock bindings with "fin_pll" clock-output-name.
- That clock is being passed internally to the 9 PLLs.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5410.h header and can be used in device
-tree sources.
-
-Example 1: An example of a clock controller node is listed below.
-
- fin_pll: xxti {
- compatible = "fixed-clock";
- clock-frequency = <24000000>;
- clock-output-names = "fin_pll";
- #clock-cells = <0>;
- };
-
- clock: clock-controller@10010000 {
- compatible = "samsung,exynos5410-clock";
- reg = <0x10010000 0x30000>;
- #clock-cells = <1>;
- clocks = <&fin_pll>;
- };
-
-Example 2: UART controller node that consumes the clock generated by the clock
- controller. Refer to the standard clock bindings for information
- about 'clocks' and 'clock-names' property.
-
- serial@12c20000 {
- compatible = "samsung,exynos4210-uart";
- reg = <0x12C00000 0x100>;
- interrupts = <0 51 0>;
- clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
- clock-names = "uart", "clk_uart_baud0";
- };

-A subset of above clocks available on given board shall be specified in
