This leads to a WARN()[1]. The orientation property is known earlier. For example, some panels parse the property through device tree during probe. The series add a panel API drm_panel_get_orientation() for drm/kms drivers. The drivers can use the API to get panel's orientation, so they can call drm_connector_set_panel_orientation() before drm_dev_register(). Panel needs to implement .get_orientation callback to return the property.
