[PATCH] virtio-ccw: Switch to device/driver language.

[Cornelia Huck <cornelia.huck@de.ibm.com>]

Switch the parts of the virtio-ccw specification that did not already
to device/driver instead of guest/host. For more general discussions,
host/guest is kept (like when talking about guest<->host notifications
in general). This should make things more consistent.
