Also allows you to have up to 40b offset, which might be important

Not with the current generation I think, since the mbus windows are
32 bit only, but it would avoid having to come up with a new format
for a potential future-generation mbus that has wider address.
Yeah, I also recall Thomas or Gregory mention a 32b limitation in
remap windows. But we don't need to waste addresses here
And even if SIAA0000 is a concern because there may be target id >15
someday, we can still have IIAASS00 instead of IIAA00SS. I guess
LPAE will not rise above 40b quickly ;)
