They're the same macros underneath. Drop pXd_is_leaf(), instead always use
pXd_leaf().
At the meantime, instead of renames, drop the pXd_is_leaf() fallback
definitions directly in arch/powerpc/include/asm/pgtable.h. because similar
fallback macros for pXd_leaf() are already defined in
include/linux/pgtable.h.
