drm/rockchip: vop2: Add YUV support to background color
The VOP2 background color must be programmed with 10-bit precision,
using YUV format when the overlay operates in YUV mode, and RGB
otherwise.
Add the required RGB-to-YCbCr conversion logic, covering all color
spaces supported by the display controller: BT601L, BT601F, BT709L and
BT2020L.
Since the color is currently programmed to hardware on every atomic
commit, minimize the computation cost by splitting the work across the
two paths: in atomic_enable(), perform the conversion unconditionally
(the hardware state is unknown after power-on), while in atomic_flush(),
perform it only when the DRM property has actually changed.
