powerpc/mm/hash: Don't memset pgd table if not needed
We need to zero-out pgd table only if we share the slab cache with pud/pmd level caches. With the support of 4PB, we don't share the slab cache anymore. Instead of removing the code completely hide it within an #ifdef. We don't need to do this with any other page table level, because they all allocate table of double the size and we take of initializing the first half corrrectly during page table zap.
