drm/i915: Share {csc,gamma}_enable calculation for ilk/snb vs. ivb+

Browse source

ilk/snb vs. ivb+ hardware is mostly identical except for the addition
of the split gamma mode on ivb. Thus we can share the csc_enable
and gamma_enable calculation for both variants. Pull that stuff
into a few helpers.

Note that this also fills in the missing ctm/degamma stuff into
ilk_color_check() pretty much, so for good measure let's also
add a few extra checks relating to that, although we still don't
expose ctm/degamma to userspace. But now it'll be trivial to do
so if we wish.
