powerpc/mm: Introduce early_init_mmu() on 64-bit
This moves some MMU related init code out of setup_64.c into hash_utils_64.c and calls it early_init_mmu() and early_init_mmu_secondary(). This will make it easier to plug in a new MMU type. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
