mm/debug_vm_pgtable: replace pte_mkhuge() with arch_make_huge_pte()

Since the following commit arch_make_huge_pte() should be used directly in
generic memory subsystem as a platform provided page table helper, instead
of pte_mkhuge().  Change hugetlb_basic_tests() to call
arch_make_huge_pte() directly, and update its relevant documentation entry
as required.
