powerpc: Trivially merge several headers from asm-ppc64 to asm-powerpc
For these, I have just done the lame-o merge where the file ends up
looking like:
#ifndef CONFIG_PPC64
#include <asm-ppc/foo.h>
#else
... contents from asm-ppc64/foo.h
#endif
so nothing has changed, really, except that we reduce include/asm-ppc64
a bit more.
