A first step towards getting rid of register_device_unmigratable
(ivshmem and lacking vmstate support in virtio are blocking this):
Allow to register an unmigratable vmstate via qdev, i.e. tag a device
declaratively.
I thought part of the problem with this was that for some devices (like
ivshmem), whether it can be migrated was dynamic. It depends on
configuration, state, etc.
