Your device is multi-function. Create an MFD driver for it. Make the
8250 driver bind to the MFD, and provide your own baud rate methods
within the standard 8250 layer

Implement the GPIO lines in a GPIO driver that also binds to the MFD and
lives in drivers/gpio

All the needed pieces already exist to implement it cleanly this way
without duplicating a ton of code.
