I think there is no difference, and I don't think moving out of sysbus 
is really a goal that we need to pursue.

I agree with Andreas that having a "SoC object" as father of sysbus 
(instead of "nothing at all") would be slightly better.

We could also make TYPE_MACHINE a subclass of TYPE_DEVICE, to have an 
obvious place for this SoC object.
