This removes the power specific stubs created by commit aad71e3928be
("powerpc/mm: Fix build break with RADIX=y & HUGETLBFS=n") used when
!CONFIG_HUGETLB_PAGE. Instead, it addresses the build break by
getting the definitions from <linux/hugetlb.h>. This allows the
macros in <linux/hugetlb.h> to be replaced with static inlines.
