[Qemu-devel] [PATCH v5 4/7] virtio-serial-ccw: switch to the new API.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

Here the virtio-serial-ccw is modified for the new API. The device
virtio-serial-ccw extends virtio-ccw-device as before. It creates and
connects a virtio-serial during the init. The properties are not modified.
