This will add edid support to all virtual connectors. Probably a bit much,
and I don't think what everyone else wants for their virtual hw drivers.

I think better to wrap a new drm_connector_attach_edid_property(), which
virtual drivers can call when needed. Also: Might be good to update the
kerneldoc, and perhaps double-check no userspace will go boom on this
change (yes I'm paranoid).
