xtensa: switch to generic version of pte allocation
xtensa clears PTEs during allocation of the page tables and pte_clear()
sets the PTE to a non-zero value. Splitting ptes_clear() helper out of
pte_alloc_one() and pte_alloc_one_kernel() allows reuse of base generic
allocation methods (__pte_alloc_one() and __pte_alloc_one_kernel()) and
the common GFP mask for page table allocations.
The pte_free() and pte_free_kernel() implementations on xtensa are
identical to the generic ones and can be dropped.
