Thomas reported that the subchannel for a  3270 device that ended up
in a broken state (status pending even though not enabled) did not
get out of that state even after a reboot (which involves a subsytem
reset). The reason for this is that the 3270 device did not define
a reset handler.

Let's fix this by introducing a base reset handler (set up for all
ccw devices) that resets the subchannel and have virtio-ccw call
its virtio-specific reset procedure in addition to that.

The 'all' from the subject is actually 'all except maybe vfio-ccw'
