powerpc/mm: Move get_unmapped_area functions to slice.c
hugetlb_get_unmapped_area() is now identical to the
generic version if only RADIX is enabled, so move it
to slice.c and let it fallback on the generic one
when HASH MMU is not compiled in.
Do the same with arch_get_unmapped_area() and
arch_get_unmapped_area_topdown().
