media: dt-bindings: media: convert rockchip rga bindings to yaml 

Current dts files for Rockchip with 'rga' nodes
are manually verified. In order to automate this process
rockchip-rga.txt has to be converted to yaml.

Changed:
  Add missing reg property

device-tree bindings for rockchip 2D raster graphic acceleration controller (RGA)
RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
graphics operations, such as point/line drawing, image scaling, rotation,
BitBLT, alpha blending and image blur/sharpness.
Required properties:
- compatible: value should be one of the following
"rockchip,rk3228-rga", "rockchip,rk3288-rga": for Rockchip RK3228
"rockchip,rk3288-rga": for Rockchip RK3288
"rockchip,rk3399-rga": for Rockchip RK3399
- interrupts: RGA interrupt specifier.
- clocks: phandle to RGA sclk/hclk/aclk clocks
- clock-names: should be "aclk", "hclk" and "sclk"
- resets: Must contain an entry for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: should be "core", "axi" and "ahb"
Example:
SoC-specific DT entry:
rga: rga@ff680000 {
compatible = "rockchip,rk3399-rga";
reg = <0xff680000 0x10000>;
interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA_CORE>;
clock-names = "aclk", "hclk", "sclk";
resets = <&cru SRST_RGA_CORE>, <&cru SRST_A_RGA>, <&cru SRST_H_RGA>;
reset-names = "core, "axi", "ahb";
};
