From: Ville Syrjälä <ville.syrj...@linux.intel.com> Add support for underscan by exposing the margin properties on ilk+ HDMI ports. This can be useful with silly TVs that won't let you disable overscanning.
We limit this to ilk+ only because the gmch style panel fitter doesn't really have the flexibility we need.
