mm/hugetlb: enable PUD level huge page migration
Architectures like arm64 have PUD level HugeTLB pages for certain configs
(1GB huge page is PUD based on ARM64_4K_PAGES base page size) that can
be enabled for migration. It can be achieved through checking for
PUD_SHIFT order based HugeTLB pages during migration.
