From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
We're going to want different behavior for skl/glk vs. icl
in .color_commit_noarm(), so split the hook into two. Arguably
we already had slightly different behaviour since
csc_enable/gamma_enable are never set on icl+, so the old
code was perhaps a bit confusing as well.
