parisc: switch to generic version of pte allocation
parisc allocates PTE pages with __get_free_page() and uses
GFP_KERNEL | __GFP_ZERO for the allocations.
Switch it to the generic version that does exactly the same thing for the
kernel page tables and adds __GFP_ACCOUNT for the user PTEs.
The pte_free_kernel() and pte_free() versions on are identical to the
generic ones and can be simply dropped.
