I guess no, it's now cpu-as-device that should be next on a queue, since I'm
rewriting this series to use static properties instead so CPU must be a
device.

Though work would be easier if static props we written&applied on top of
this, it's not like we need working for CPU qdev_prop_set_globals() after this
series.
