[Intel-gfx] [PATCH 5/6] drm/i915: Enable pipe gamma for the overlay

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We pass the plane data through the pipe gamma for all the other
planes. Can't see why we should treat the overlay differently,
so let's enable pipe gamma for it as well.
