s390x: allow cpu hotplug via device_add
E.g. the following now works:
device_add host-s390-cpu,id=cpu1,core-id=1
The system will perform the same checks as when using cpu_add:
- If the core_id is already in use
- If the next sequential core_id isn't used
- If core-id >= max_cpu is specified
In addition, mixed CPU models are checked. E.g. if starting with
-cpu host and trying to hotplug "qemu-s390-cpu":
"Mixed CPU models are not supported on s390x."
