powerpc/book3s64/pkeys: Fixup bit numbering

Browse source 
This number the pkey bit such that it is easy to follow. PKEY_BIT0 is
the lower order bit. This makes further changes easy to follow.

No functional change in this patch other than linux page table for
hash translation now maps pkeys differently.
