You can't move the class registering into device_t as e.g. the network
class has to know the ifp. The shutdown hook can be directly shared
between frontend already if all do the same thing. If all your frontends
directly call the backend, you can also push the register calls down.
I still don't see what splitting between bus-dependent and
bus-indepedent for the suspend/resume (and shutdown) hooks really buys.
