openrisc does nothing special in the io accessors, so use the generic
ones as the kernel.

x86: ns16550: Rework driver to allow for x86 I/O space

The current implementation fakes a memory-mapped I/O device
at 0x3f8 and 0x2f8, then uses platform read/write functions
to do the actual reading and writing. These platform functions
only exist for the x86 platform; better to move the I/O
routines into the driver and have the driver request I/O ports
using request_ioport_region.
