mm: add new arch_make_huge_pte() method for tile support
The tile support for multiple-size huge pages requires tagging
the hugetlb PTE with a "super" bit for PTEs that are multiples of
the basic size of a pagetable span. To set that bit properly
we need to tweak the PTe in make_huge_pte() based on the vma.
This change provides the API for a subsequent tile-specific
change to use.
