[PATCH v7 3/7] powerpc: mm: Replace p{u,m,4}d_is_leaf with p{u,m,4}_leaf
Replace occurrences of p{u,m,4}d_is_leaf with p{u,m,4}_leaf, as the
latter is the name given to checking that a higher-level entry in
multi-level paging contains a page translation entry (pte) throughout
all other archs.
A future patch will implement p{u,m,4}_leaf stubs on all platforms so
that they may be referenced in generic code.

V4: New patch
V5: Previously replaced stub definition for *_is_leaf with *_leaf. Do
that in a later patch
