To be clear, only 64-bit hash.

In theory there's no reason we can't *always* mark the page tables as BE, after
all everything other than the new ppc64le systems are BE.

But looking at it, that will cause knock-on effects in a few places. So we
won't do it now. But it would be a good clean-up in the medium term I think. It
would get us back to a single pgtable-types.h.

So everyone keeps telling me :)

Where is this specified? I can't find it in the ISA. But I must be searching
for the wrong words.
