powerpc: Fix build error for book3e
We moved the definition of shift_to_mmu_psize and mmu_psize_to_shift
out of hugetlbpage.c in patch "powerpc: New hugepage directory format".
These functions are not related to hugetlbpage and we want to use them
outside hugetlbpage.c We missed a definition for book3e when we moved
these functions. Add similar functions to mmu-book3e.h
