The previous patch moved virtual css bridge and bus out from virtio-ccw, but kept the direct reference of virtio-ccw specific unplug function inside css-bridge.c. To make the virtual css bus and bridge useful for non-virtio devices, this introduces a common unplug function pointer "unplug" to call specific virtio-ccw unplug parts. Thus, the tight coupling to virtio-ccw can be removed. This unplug pointer is a member of CCWDeviceClass, which is introduced as an abstract device layer called "ccw-device". This layer is between DeviceState and specific devices which are plugged in virtual css bus, like virtio-ccw device. The specific unplug handlers should be assigned to "unplug" during initialization.
