update compatible, remove obsolete properties "fsl,spi-num-chipselects"
and update the example based on latest DT file.

-* Freescale (Enhanced) Configurable Serial Peripheral Interface
- (CSPI/eCSPI) for i.MX
-
-Required properties:
-- compatible :
- - "fsl,imx1-cspi" for SPI compatible with the one integrated on i.MX1
- - "fsl,imx21-cspi" for SPI compatible with the one integrated on i.MX21
- - "fsl,imx27-cspi" for SPI compatible with the one integrated on i.MX27

- - "fsl,imx8mn-ecspi" for SPI compatible with the one integrated on i.MX8MN
- - "fsl,imx8mp-ecspi" for SPI compatible with the one integrated on i.MX8MP
-- reg : Offset and length of the register set for the device
-- interrupts : Should contain CSPI/eCSPI interrupt
-- clocks : Clock specifiers for both ipg and per clocks.
-- clock-names : Clock names should include both "ipg" and "per"
-See the clock consumer binding,
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Recommended properties:
-- cs-gpios : GPIOs to use as chip selects, see spi-bus.txt. While the native chip
-select lines can be used, they appear to always generate a pulse between each
-word of a transfer. Most use cases will require GPIO based chip selects to
-generate a valid transaction.
-
-Optional properties:
-- num-cs : Number of total chip selects, see spi-bus.txt.
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names: DMA request names, if present, should include "tx" and "rx".
-- fsl,spi-rdy-drctl: Integer, representing the value of DRCTL, the register
-controlling the SPI_READY handling. Note that to enable the DRCTL consideration,
-the SPI_READY mode-flag needs to be set too.
-Valid values are: 0 (disabled), 1 (edge-triggered burst) and 2 (level-triggered burst).
-
-Obsolete properties:
-- fsl,spi-num-chipselects : Contains the number of the chipselect
-
-Example:
-
-ecspi@70010000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,imx51-ecspi";
- reg = <0x70010000 0x4000>;

- cs-gpios = <&gpio3 24 0>, /* GPIO3_24 */
- <&gpio3 25 0>; /* GPIO3_25 */

-* Freescale Low Power SPI (LPSPI) for i.MX
-
-Required properties:
-- compatible :
- - "fsl,imx7ulp-spi" for LPSPI compatible with the one integrated on i.MX7ULP soc
- - "fsl,imx8qxp-spi" for LPSPI compatible with the one integrated on i.MX8QXP soc
-- reg : address and length of the lpspi master registers
-- interrupt-parent : core interrupt controller
-- interrupts : lpspi interrupt
-- clocks : lpspi clock specifier. Its number and order need to correspond to the
- value in clock-names.
-- clock-names : Corresponding to per clock and ipg clock in "clocks"
- respectively. In i.MX7ULP, it only has per clk, so use CLK_DUMMY
- to fill the "ipg" blank.
-- spi-slave : spi slave mode support. In slave mode, add this attribute without
- value. In master mode, remove it.
-
-Examples:
-
-lpspi2: lpspi@40290000 {
- compatible = "fsl,imx7ulp-spi";
- reg = <0x40290000 0x10000>;
