From: Ville Syrjälä <ville.syrj...@linux.intel.com>
The current intel_color_check() is a mess, and worse yet it is
in fact incorrect for several platforms. The hardware has
evolved quite a bit over the years, so let's just go for a clean
split between the platforms by turning this into a vfunc.
The actual work to split it up will follow.
