powerpc/32: refactor pmd_offset(pud_offset(pgd_offset...
At several places pmd pointer is retrieved through the same action:
pmd = pmd_offset(pud_offset(pgd_offset(mm, addr), addr), addr);
or
pmd = pmd_offset(pud_offset(pgd_offset_k(addr), addr), addr);
Refactor this by implementing two helpers pmd_ptr() and pmd_ptr_k()
This will help when adding the p4d level.
