While at it, re-enable high baud rates.

Jay, can you, please, test this on as many hardware as you have?

The series depends on the fix-series:

serial: 8250_pci: Split out Pericom driver

serial: 8250_pericom: Re-enable higher baud rates

I have my current state here:

* 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.
