[PATCH] ppc32 8xx: use io accessor macros instead of direct memory reference
Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct memory references. Other than making IO accesses explicit (which is a plus for readability), a common set of macros provides a unified place for the volatile flag to constraint compiler code reordering. There are several unlucky places at the moment which lack the volatile flag.
