[Intel-gfx] [PATCH 08/11] drm/i915: Reuse ilk_gamma_mode() on ivb+

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Apart from the split gamma mode ivb+ LUTs work just like ilk+ LUTs.
So let's handle the special case, and then just fall back to
ilk_gamma_mode() to avoid having to duplicate the same logic.
