No support for CONFIG_SERIAL_MULTI. Simple conversion possible, though this
driver in fact contains two drivers in total.
23) serial_pxa.c

This driver is a bit complicated, but due to clean support for
CONFIG_SERIAL_MULTI, there are no expected obstructions throughout the
conversion process.
24) serial_s3c24x0.c

This driver, being quite ad-hoc might need some work to bring back to shape.
