[PATCH v2 3/8] drm/mediatek: dp: Always return connected status for eDP in .detect()

If this is an eDP panel it's not removable, hence it's always connected:
as a shortcut, always return connector_status_connected in the .detect()
callback for eDP connector, avoiding a poweron, a check for sink count
and a poweroff.
