powerpc: Hugetlb pgtable cache access cleanup

Andrew Morton suggested that using a macro that makes an array
reference look like a function call makes it harder to understand the
code.

This therefore removes the huge_pgtable_cache(psize) macro and
replaces its uses with pgtable_cache[HUGE_PGTABLE_INDEX(psize)].
