[S390] cio: introduce notifier for boxed state
If a ccw device did not respond in time during internal io, we set it
into boxed state. With this patch we have the following behaviour:
* the ccw driver will get a notification if the device was online and
goes into the boxed state
* if the device was disconnected and got boxed nothing special is to be
done (it will be handled in reprobing later)
* if the device got boxed while initial sensing it will be unregistered
