serial: register vmsd with DeviceClass
Migration from old to new code works, however the other way fails for devices that use serial_init/serial_mm_init with "base", used as instance_id previously. (with qdev_set_legacy_instance_id, the alias_id is only used in savevm.c:find_se(), and thus can only be used to match against "legacy" instance id values. On new code, instance_id is generated incrementally from 0 with calculate_new_instance_id(), based on "qdev-path/vmsd-name") Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: xiaoqiang zhao <zxq_yx_007@163.com>
