PPC: add accessor macros to clear and set bits in one shot

PPC: add accessor macros to clear and set bits in one shot

This patch adds macros from linux/include/asm-powerpc/io.h to clear and
set bits in one shot using the in_be32, out_be32, etc. accessor functions.
They are very handy to manipulate bits it I/O registers.

This patch is required for my forthcoming FSL NAND UPM driver re-write and
the support for the TQM8548 module.
