drm/i915: Extract chv_color_check()

Browse source

Since CHV has the CGM unit we require a custom implementation
of .color_check().

This fixes the computation of gamma_enable as previously we
left it enabled even when were using the CGM gamma instead.
Now we turn off the legacy LUT unless it's actually required.

v2: Add some comment explaining the color pipeline (Matt)
