powerpc: Fix build error with 64K pages and !hugetlbfs
HAVE_ARCH_UNMAPPED_AREA and HAVE_ARCH_UNMAPPED_AREA_TOPDOWN must be defined whenever CONFIG_PPC_MM_SLICES is enabled, not just when CONFIG_HUGETLB_PAGE is. They used to be always defined together but this is no longer the case since 3a8247cc2c856930f34eafce33f6a039227ee175 ("powerpc: Only demote individual slices rather than whole process").
