40e8550afc powerpc/mm: Move WIMG update to helper. 
Only difference here is, we apply the WIMG mapping early, so rflags
passed to updatepp will also be changed.

c6a3c495f0 powerpc/mm: Add helper for converting pte bit to hpte bits 
Instead of open coding it in multiple code paths, export the helper
and add more documentation. Also make sure we don't make assumption
regarding pte bit position
