[PATCH 05/11] drm/i915: Pass the whole atomic state to intel_color_prepare_commit()

[Ville Syrjala <ville.syrjala@xxxxxxxxxxxxxxx>]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

We'll have need to examine both the old and new crtc states in
intel_color_prepare_commit(), so let's just pass in the whole
atomic state.
