We are not supposed to spread quirks in 8250_port module especially
when we have a separate driver for the hardware in question.
Move quirk from generic module to the driver that uses it.
While at it, move IO to ->set_divisor() callback as it has to be from
day 1. ->get_divisor() is not supposed to perform any IO as UART port:
- might not be powered on
- is not locked by a spin lock
