drm: Automatically register/unregister all connectors

As the drm_connector is now safe for multiple calls to
register/unregister, automatically perform a registration on all known
connectors drm drv_register (and unregister from drm_drv_unregister).
Drivers can still call drm_connector_register() and
drm_connector_unregister() individually, or defer as required.
