I'm hesitant to expose a tty device on top of serdev to userspace that
we then have to support forever unless that's the only way tty devices
(for serial ports) are created.
I did a similar patch which just registered both serdev and a tty
allowing them to coexist. It suffered from warnings about open counts
though and felt hacky.
