drm/amd/display: Update color space, bias and scale programming sequence 



[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.
