[PATCH 1/5] [media] rockchip/rga: v4l2 m2m support

Rockchip RGA is a separate 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. The drvier is mostly based on s5p-g2d v4l2 m2m driver. And supports various operations from
