Hmm, looks good. But it makes me wonder if we should now try to remove
the second call to tty_port_link_device()?

Now we have a number of helpers that do that tty_port_link_device()
call for the driver (eg tty_port_register_device_attr_serdev(),
tty_port_register_device_attr(), and the just added
uart_add_one_port()).

But we also have drivers doing it by hand, and presumably we now have
drivers that do it through multiple paths? I guess it's harmless, but
it feels a bit odd. No?
