And it seems to just be another 165x0 driver anyway In fact it looks
like the right thing to do is to take it out and shoot it. We've got a
16x50 driver already.

There are a few bits of gunk in there to set custom board registers and
to figure out the configuration. See drivers/tty/serial/8250/8250_pci.c
and it ought to be possible to just plug it in there. The 422 stuff
might need a bit more tweaking.
