For ilk, add hw read out to create hw blob of gamma
lut values.

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 ilk_get_color_config() to ilk_read_luts() [Ville]
v9:  -80 character limit [Uma]
     -Made read func para as const [Ville, Uma]
     -Renamed ilk_read_gamma_lut() to ilk_read_lut_10() [Uma, Ville]
v10: -Made ilk_read_luts() static [Jani]
     -ilk_load_lut_10 has lut_size, not (lut_size - 1) [Jani]
