drm/i915/display: Extract i965_read_luts()
For i965, add hw read out to create hw blob of gamma
lut values.
Review comments from old series:
https://patchwork.freedesktop.org/series/58039/
v4: -No need to initialize *blob [Jani]
-Removed right shifts [Jani]
-Dropped dev local var [Jani]
v5: -Returned blob instead of assigning it internally
within the function [Ville]
-Renamed i965_get_color_config() to i965_read_lut() [Ville]
-Renamed i965_get_gamma_config_10p6() to i965_read_gamma_lut_10p6()
[Ville]
v9: -Typo and 80 character limit [Uma]
-Made read func para as const [Ville, Uma]
-Renamed i965_read_gamma_lut_10p6() to i965_read_lut_10p6() [Ville, Uma]
v10: -Swapped ldw and udw while creating hw blob [Jani]
-Added last index rgb lut value from PIPEGCMAX to h/w blob [Jani]
