drm/i915/display: Add func to compare hw/sw gamma lut
Add func intel_color_lut_equal() to compare hw/sw gamma
lut values. Since hw/sw gamma lut sizes and lut entries comparison
will be different for different gamma modes, add gamma mode dependent
checks.
v3: -Rebase
v4: -Renamed intel_compare_color_lut() to intel_color_lut_equal() [Jani]
-Added the default label above the correct label [Jani]
-Corrected smatch warn "variable dereferenced before check"
[Dan Carpenter]
v5: -Added condition (!blob1 && !blob2) return true [Jani]
v6: -Made patch11 as patch3 [Jani]
v8: -Split patch 3 into 4 patches
-Optimized blob check condition [Ville]
v9: -Exclude spilt gamma mode (bdw and ivb platforms)
as there is exception in way gamma values are written in
hardware [Ville]
-Added exception made in commit [Uma]
-Dropped else, character limit and indentation [Uma]
-Added multi segmented gama mode for icl+ platforms [Uma]
v10: -Dropped multi segmented mode for icl+ platforms [Jani]
-Removed references of sw and hw state in compare code [Jani]
-Dropped inline from func [Jani]
