From: Peter Ujfalusi <peter.ujfal...@ti.com>
When the connector associated detect callback is not provided, we can not
detect if the display is connected or disconnected. These displays does not
support hot plug, they are always connected. Let DRM know that connectors
w/o detect callback should not be polled.
