arm64: mm: Route pmd thp functions through pte equivalents
Rather than have separate hugetlb and transparent huge page pmd manipulation functions, re-wire our thp functions to simply call the pte equivalents. This allows THP to take advantage of the new PTE_WRITE logic introduced in: c2c93e5 arm64: mm: Introduce PTE_WRITE To represent splitting THPs we use the PTE_SPECIAL bit as this is not used for pmds.
