Enable serdev support by using the serdev opt-in tty-port registration
helpers.
FIXME: serdev core always allocates and registers a serdev controller
during port registration only to immediately roll back in the common
case when there is no serdev slave defined in firmware
FIXME: serdev does not support hotplugging (e.g. tty port hangups)
