The commit message could contain some words about how ugly this used to
be and how beautiful it is now. Awesome.
One bug, comment inline.

Should be ivb_load_luts.

Should be NULL.
Old code for ivb i.e. non-hsw gen 7 was:
- } else if (DISPLAY_VER(dev_priv) >= 7) {
- dev_priv->color_funcs.load_luts = ivb_load_luts;
- } else {
Right? It's a nightmare to review this because the old code was a
nightmare to read.
I think with that fixed this is good, and,
