MDEV_ID_VHOST isn't used yet here. Also, given the strong
interdependence between the class_id and the ops structure, we might
wand to define them in the same place. Thanks,

Rethink about this, consider we may have more types of devices supported
in the future, moving all device_ops to mdev.h seems unnecessary. I
prefer to keep the device_ops into their own headers.
Thanks
