drm_dev_register() sets connector->registration_state to
DRM_CONNECTOR_REGISTERED and dev->registered to true. If
drm_connector_set_panel_orientation() is first called after
drm_dev_register(), it will fail several checks and results in following
warning.
Create panel orientation property in drm_connector_init()
and set default value to UNKNOWN. Let the panel set the real value
later.

A bit silly to add this to every connector. I think you should just
fix the driver/bridge stuff to set up the orientaion earlier.
