We want the regs to be padded to the address width to make it easier for
humans to sort the nodes. At least for me it's easy to compare a 3-digit
address with a 4-digit one, so I haven't felt the need to enforce it
here.

But I certainly don't mind.

Yes, that is required by the binding.

I added that and picked up the 3 patches. Thanks for reviewing Konrad,
and thanks for the patches Bhupesh.
