m66592-udc is erroneously using PIO routines on MMIO registers, which presently blows up for any platform that elects to either override or do away with PIO routines. This managed to work for the common cases since the PIO routines were simply wrapped to their MMIO counterparts. This switches over to using the MMIO routines directly, and enables us to kill off a lot of superfluous casting in the process.
