From: Chris Park <chris.park@xxxxxxx>
[Why]
DMColor inaccurately updates color space, bias and scale
destructively in dc_plane_state. This can be resolved by
accurately populating the infos on dc_plane_info where then
translation to plane state can happen as a whole surface update sequence.
[How]
Remove dc_plane_state update in DMColor and update color space,
bias and scale on dc_plane_info.
