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?

The series depends on the fix-series: https://lore.kernel.org/linux-serial/20211117145502.43645-1-andriy.shevchenko@linux.intel.com/T/#u (local)

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.
