[POWERPC] Use mtocrf instruction in asm when CONFIG_POWER4_ONLY=y
mtocrf is a faster single-field mtcrf (move to condition register
fields) instruction available in POWER4 and later processors.  It can
make quite a difference in performance on some implementations, so use
it for CONFIG_POWER4_ONLY builds.

powerpc: Rename files to have consistent _32/_64 suffixes
This doesn't change any code, just renames things so we consistently
have foo_32.c and foo_64.c where we have separate 32- and 64-bit
versions.
