SERIAL: Enable port-mapped access
The x86 architecture exclusively uses Port-Mapped I/O (inb/outb) to access the 16550 UARTs. This patch mimics how Linux selects between Memory-Mapped and Port-Mapped I/O. This allows x86 boards to use CONFIG_SERIAL_MUTLI and drop the custom serial port driver Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
