Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic Video Controller over to YAML schemas.
This yaml bindings will then be extended to support new SoCs.

-Amlogic Video Decoder
-================================
-
-The video decoding IP lies within the DOS memory region,
-except for the hardware bitstream parser that makes use of an undocumented
-region.
-
-It makes use of the following blocks:
-
-- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
-then feed from this VIFIFO.
-- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
-- VDEC_HEVC can decode HEVC and VP9.
-
-Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
-concurrently.
-
-Device Tree Bindings:
----------------------
-
-VDEC: Video Decoder
---------------------------
-
-Required properties:
-- compatible: value should be different for each SoC family as :
- - GXBB (S905) : "amlogic,gxbb-vdec"
- - GXL (S905X, S905D) : "amlogic,gxl-vdec"
- - GXM (S912) : "amlogic,gxm-vdec"
- followed by the common "amlogic,gx-vdec"
-- reg: base address and size of he following memory-mapped regions :
- - dos
- - esparser
-- reg-names: should contain the names of the previous memory regions
-- interrupts: should contain the following IRQs:
- - vdec
- - esparser
-- interrupt-names: should contain the names of the previous interrupts
-- amlogic,ao-sysctrl: should point to the AOBUS sysctrl node
-- amlogic,canvas: should point to a canvas provider node
-- clocks: should contain the following clocks :
- - dos_parser
- - dos
- - vdec_1
- - vdec_hevc
-- clock-names: should contain the names of the previous clocks
-- resets: should contain the parser reset
-- reset-names: should be "esparser"
-
-Example:
-
-vdec: video-codec@c8820000 {
- compatible = "amlogic,gxbb-vdec", "amlogic,gx-vdec";
- reg = <0x0 0xc8820000 0x0 0x10000>,
- <0x0 0xc110a580 0x0 0xe4>;
- reg-names = "dos", "esparser";
-
- interrupts = <GIC_SPI 44 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 32 IRQ_TYPE_EDGE_RISING>;
- interrupt-names = "vdec", "esparser";
-
- amlogic,ao-sysctrl = <&sysctrl_AO>;
- amlogic,canvas = <&canvas>;
-
- clocks = <&clkc CLKID_DOS_PARSER>,
- <&clkc CLKID_DOS>,
- <&clkc CLKID_VDEC_1>,
- <&clkc CLKID_VDEC_HEVC>;
- clock-names = "dos_parser", "dos", "vdec_1", "vdec_hevc";
-
- resets = <&reset RESET_PARSER>;
- reset-names = "esparser";

Add bindings to support the Amlogic Video Decoder on the Amlogic G12A
family.
For the G12A family, a supplementary clock is needed to operate the
HEVC/VP9 decoder.
