Generic PTE range and remapping helpers now pass pointers to PTE table
storage as hw_pte_t *. Update the Xen callbacks to match those interfaces.
Keep logical PTE values as pte_t and continue to access them through the
existing PTE helpers. This is required when Xen is built for an
architecture that selects the distinct hw_pte_t wrapper.
