[PATCH RFC 11/11] xen: use hw_pte_t for PTE range callbacks

[Muhammad Usama Anjum]

Generic PTE range and remapping helpers now pass pointers to PTE table
storage as hw_pte_t *. Update the callbacks to match those interfaces.

Keep logical PTE values as pte_t and continue to access them through the
existing PTE helpers.
