powerpc/mm: move update_mmu_cache() into book3s hash utils.
update_mmu_cache() is only for BOOK3S, and can be simplified for
BOOK3S32.
Move it out of mem.c into respective BOOK3S32 and BOOK3S64 files
containing hash utils.
BOOK3S64 version of hash_preload() is only used locally, declare it
static.
Remove the radix_enabled() stuff in BOOK3S32 version.
