[PATCH 0/3] drm/i915: VLV color range stuff

[ville.syrjala at linux.intel.com (ville.syrjala at linux.intel.com)]

This is an attempt to make the RGB output color range selection work on VLV.

I also decided to refactor the <=gen4 PIPECONF setup code, so that it looks a
bit more like the the ILK/HSW codepaths.

So far this is only compile tested.
