[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.
