You are right, this is a bit nasty, it should not attempt to do this.
Basically the reg parsing logic has a hack to work around apply PowerMac
firmware that misses some "ranges" properties.
I think we should change the DT parsing code to not create those
resources if there is a bus that can't be translated.
