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";
-	};
