drm: add connector info/property for non-desktop displays [v2]
This adds the infrastructure needed to quirk displays
using edid and to mark them a non-desktop.
A non-desktop display is one which shouldn't normally be included
as a part of a desktop environment.
This is meant to cover head mounted devices like HTC Vive.
v2: Change description from non-standard to non-desktop, add docs
