This sorts out the sdio uart handling of the tty layer. The existing code
has lots of races and other fun bugs. Beat it into the current tty format for
hotpluggable devices. The updates are intentionally modelled on Alan Stern's
USB serial approach which is defintiely "best practice" right now. Also clean
it up as we go and sort the circ stuff out.
I don't have hardware to test this so hopefully someone out there does,
otherwise given the nature of the bugs involved the driver will be progressed
to BROKEN and removal.
