VOP not support pre-alpha when overlay at YUV domain,
so we set VOP overlay at RGB domain.
If open BCSH and output_color is RGB,must open R2Y&Y2R,
if output_color is YUV,must open R2Y.
In case of tSD board or SD booting project, BSP engineers could
only add "supports-tSD" into emmc_of_node claim. Refer to arch/arm/boot/dts/rk3288-tb.dts
