This change enables the config option ARCH_ENABLE_HUGEPAGE_MIGRATION
depending on whether the platform has got ARCH_WANT_GENERAL_HUGETLB
or not along with config option MIGRATION. In turn, it turns on the
'hugepage_migration_supported' function which is checked for feature
presence during HugeTLB page migration and clears the way.
