mm/powerpc: replace pXd_is_leaf() with pXd_leaf()

Browse Source 
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.
