powerpc/mm: Use a helper for finding pte bits mapping I/O area
Use a helper instead of open coding with constants. A later patch will drop the WIMG bits and use PowerISA 3.0 defines. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
