[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.
