[PATCH] drm: ignore disconnected <-> unknown status changes

[Knut Petersen]

On an AOpen i915GMm-hfs the hotplug events generated
by transitions between connector_status_unknown and
connector_status_disconnected cause screen distortions.

The attached patch cures the problem by disabling the
generation of hotplug events in those cases. That should
be safe for everybody as the only relevant changes are
those from / to connector_status_connected.
