I915 driver registers gamma correction as palette correction
property with DRM layer. This patch adds set_property() and get_property()
handlers for pipe level gamma correction.

The set function attaches the Gamma correction blob to CRTC state, these
values will be committed during atomic commit.

A user can trigger this error on demand, so I think we want to keep this
as DRM_DEBUG_KMS (same on patches #10 and 13).
