With hash translation, the hypervisor can hint the LPAR about 16GB contiguous range

only supports 1G gigantic hugepage and kernel can do the 1G gigantic hugepage
allocation via early memblock reservation. This can be done because with radix
translation pages are not required to be contiguous on the host.

Applied to powerpc/next.
