powerpc: Fix 64K page size support for PPC44x
PPC44x supports page sizes other than 4K however when 64K page sizes are selected compilation fails. This is due to a change in the definition of pgtable_t introduced by the following patch: commit 5c1f6ee9a31cbdac90bbb8ae1ba4475031ac74b4 Author: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> powerpc: Reduce PTE table memory wastage The above patch only implements the new layout for PPC64 so it doesn't compile for PPC32 with a 64K page size. Ideally we should implement the same layout for PPC32 however for the meantime this patch reverts the definition of pgtable_t for PPC32.
