We want to support real (i.e. not virtual) channel devices even for guests that do not support MCSS-E (where guests may see devices from any channel subsystem image at once). As all virtio-ccw devices are in css 0xfe (and show up in the default css 0 for guests not activating MCSS-E), we need an option to squash both the virtio subchannels and e.g. passed-through subchannels from their real css (0-3, or 0 for hosts not activating MCSS-E) into the default css. This will be exploited in a later patch.
