[PATCH] ppc: Fix arch/ppc compilation - Add missing typedef pgtable_t

Commit 2f569afd9ced9ebec9a6eb3dbf6f83429be0a7b4 ("CONFIG_HIGHPTE vs.
sub-page page tables.") breaks compilation of arch/ppc since it
introduces the pgtable_t type which was not added to arch/ppc.

This patch now adds the missing typedef.
