powerpc/mm: Drop the 64K on 4K version of pte_pagesize_index()
Now that support for 64k pages with a 4K kernel is removed, this code is unreachable. CONFIG_PPC_HAS_HASH_64K can only be true when CONFIG_PPC_64K_PAGES is also true. But when CONFIG_PPC_64K_PAGES is true we include pte-hash64.h which includes pte-hash64-64k.h, which defines both pte_pagesize_index() and crucially __real_pte, which means this definition can never be used.
