Suresh Warrier 07b1fdf5bd powerpc: Add simple cache inhibited MMIO accessors ...

Add simple cache inhibited accessors for memory mapped I/O.
Unlike the accessors built from the DEF_MMIO_* macros, these
don't include any hardware memory barriers, callers need to
manage memory barriers on their own. These can only be called
in hypervisor real mode.
