powerpc/mm: cleanup remaining ifdef mess in hugetlbpage.c
Only 3 subarches support huge pages. So when it is either 2 of them, it is not the third one. And mmu_has_feature() is known by all subarches so IS_ENABLED() can be used instead of #ifdef Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
