Peter Jin 2349236bb4 zdev: Add support for virtio devices
Add support for managing virtual I/O ccw (virtio-ccw) devices in
lszdev/chzdev.

New zdev device type virtio. Each virtio device type (blk, net,
gpu, vsock, etc.) is represented by a unique subtype of the virtio
base type.

If the virtio device type is recognized, then it will show up as
virtio-blk or virtio-net, or whatever the virtio device type is.
Otherwise, it will just show up as virtio-ccw.
