powerpc: Use RCU based pte freeing mechanism for all powerpc
Refactor the RCU based pte free code that was used on ppc64 to be used on all powerpc. Additionally refactor pte_free() & pte_free_kernel() into common code between ppc32 & ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
