In this patch, gamma and degamma hw blobs are created for BDW.
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 bdw_get_color_config() to bdw_read_luts() [Ville]
