arch/powerpc: teach book3s64 arch_get_unmapped_area{_topdown} to handle hugetlb mappings

Browse source

We want to stop special casing hugetlb mappings and make them go through
generic channels, so teach arch_get_unmapped_area{_topdown} to handle
those.

Reshuffle file_to_psize() definition so arch_get_unmapped_area{_topdown}
can make use of it.
