Actually, when I came to look at this I realised that because these
numbers are being fed into device tree it is much simpler if they are of
a fixed size rather than semantic type because you need to declare
upfront the number of 32-bit cells each address and size value in the
tree takes and it's much simpler to just declare up from "everything is
2 cells" and then use uint64_t throughout.
