From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
The gamma readout stuff was left half finished. No degamma
readout, and no readout whatsoever on ivb/bdw/skl/bxt.
Let's finish it.
Since we have the {pre,post}_csc_lut stuff this is fairly
easy to do now. The implementation of the LUT checker is
a bit more repetitive than I'd like but we an work on
shrinking it later.
There are some fixes/cleanups at the start, and while we're
in there let's also throw in the 10bit gamma mode for gen2/3.
At the end I also added a few patches to fix existing issues
with gamma vs. YCbCr/RGB limited range output.
v2: Mostly redone, only some of the readout implementations
remain more or less unchanged
