Remove the explicit calls to drm_connector_register() and
drm_connector_unregister() from the parallel RGB setup track.

For standard drivers, these operations are redundant as they are already
handled automatically under the hood by drm_dev_register() and
drm_dev_unregister() during the master device probe lifecycle.
Collapsing these calls simplifies the error unwinding path down to a
single internal memory cleanup step, as stated on the gpu todo list.
