Split Pericom driver to a separate module.
While at it, re-enable high baud rates.
Jay, can you, please, test this on as many hardware as you have?

I have my current state here:
https://github.com/accesio/linux/blob/split-pericom-driver/drivers/tty/serial/8250/8250_pericom.c
* Change port type to UPIO_PORT
* Add in pericom_do_startup() because the UPF_MAGIC_MULTIPLIER doesn't
stick.
When I'm testing baud rates greater than baud_base I'm seeing strange
things on the scope. Maybe I'm just tired, and it's human error. I
should be able to get back to it and get it done on Saturday.
