In this patch, gamma and degamma hw blobs are created for GLK.
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 glk_get_color_config() to glk_read_luts() [Ville]
-Added degamma validation [Ville]
