PPC: e500: Extend address/size of / to 64bit

We want to be able to support >= 4GB of RAM. To do so, we need to be able
to tell the guest OS how much RAM it has.

However, that information today is capped to 32bit. So let's extend the
offset and size fields to 64bit, so we can fit in big addresses and even
one day - if we wish to do so - map devices above 32bit.
