drm/i915: Introduce vfunc read_luts() to create hw lut
In this patch, a vfunc read_luts() is introduced to create a hw lut
i.e. lut having values read from gamma/degamma registers which will
later be used to compare with sw lut to validate gamma/degamma lut values.
v3: -Rebase
v4: -Renamed intel_get_color_config to intel_color_get_config [Jani]
-Wrapped get_color_config() [Jani]
v5: -Renamed intel_color_get_config() to intel_color_read_luts()
-Renamed get_color_config to read_luts
v6: -Renamed intel_color_read_luts() back to intel_color_get_config()
[Jani and Ville]
