drm/amd/display: Internal refactoring to abstract color caps
[Why&How] modules/color calculates various colour operations which are translated to abstracted HW. DCE 5-12 had almost no important changes, but starting with DCN1, every new generation comes with fairly major differences in color pipeline. We would hack it with some DCN checks, but a better approach is to abstract color pipe capabilities so modules/DM can decide mapping to HW block based on logical capabilities, Signed-off-by: Krunoslav Kovac <Krunoslav.Kovac@amd.com> Reviewed-by: Aric Cyr <Aric.Cyr@amd.com> Acked-by: Anthony Koo <Anthony.Koo@amd.com> Acked-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
