[v3 2/7] drm/i915: Define color lut range structure

Uma Shankar
2019-04-12T10:20:58Z

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

This defines the color lut ranges for 10bit and multi
segmented gamma range for ICL.

v2: Defined and advertise the gamma modes supported on
various platforms as suggested by Ville.
