Aneesh Kumar K.V 6aa59f5162 powerpc/mm: Move hash specific pte bits to be top bits of RPN
We don't support the full 57 bits of physical address and hence can
overload the top bits of RPN as hash specific pte bits.

Add a BUILD_BUG_ON() to enforce the relationship between H_PAGE_F_SECOND
and H_PAGE_F_GIX.

[mpe: Move the BUILD_BUG_ON() into hash_utils_64.c and comment it]
