Commit 15b9ca1641f0 ("drm: Config orientation property if panel provides
it") added a helper to set the panel panel orientation early but only
connected this for drm_bridge_connector, which constructs a panel bridge
with DRM_BRIDGE_ATTACH_NO_CONNECTOR and creates the connector itself.
When the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is not specified and the
panel_bridge creates its own connector the orientation is not set unless
the panel does it in .get_modes which is too late and leads to a warning
splat from __drm_mode_object_add() because the device is already
registered.
Call the necessary function to set add the orientation property when the
connector is created so that it is available before the device is
registered.
