[PATCH] powerpc: merge atomic.h, memory.h
powerpc: Merge atomic.h and memory.h into powerpc
Merged atomic.h into include/powerpc. Moved asm-style HMT_ defines from
memory.h into ppc_asm.h, where there were already HMT_defines; moved c-style
HMT_ defines to processor.h. Renamed memory.h to synch.h to better reflect
its contents.
