8250: Serial driver changes to support future Cavium OCTEON serial patches.
In order to use Cavium OCTEON specific serial i/o drivers, we first
patch the 8250 driver to use replaceable I/O functions. Compatible
I/O functions are added for existing iotypeS.
An added benefit of this change is that it makes it easy to factor
some of the existing special cases out to board/SOC specific support
code.
The alternative is to load up 8250.c with a bunch of OCTEON specific
iotype code and bug work-arounds.
