Since commit bec7cbfa7d4f ("drm/rockchip: vop2: Support setting custom
background color") the VOP2 display controller allows configuring the
background color of each video output port.However, this is currently limited to RGB formats. When operating in YUV overlay mode, the color must be programmed using YUV format. Add the necessary RGB-to-YCbCr conversion logic, covering all color spaces supported by the display controller: BT601L, BT601F, BT709L and BT2020L.
