arm: switch to generic version of pte allocation
Replace __get_free_page() and alloc_pages() calls with the generic
__pte_alloc_one_kernel() and __pte_alloc_one().
There is no functional change for the kernel PTE allocation.
The difference for the user PTEs, is that the clear_pte_table() is now
called after pgtable_page_ctor() and the addition of __GFP_ACCOUNT to the
GFP flags.
The conversion to the generic version of pte_free_kernel() removes the NULL
check for pte.
The pte_free() version on arm is identical to the generic one and can be
simply dropped.
