I'll soon send out a series that adds "device_show <qdev-path>" to
visualize the full state, something that will at least obsolete "info
pic" and "info hpet" sooner or later, maybe even more. Also, I would
like to qdev'ify CPUs in order to make them reachable for device_show
(which evaluates qdev->info.vmstate).

I'm not sure: How many use cases for a "dev_info" would remain?
Moreover, to dump statistics, we should rather add some "device_stats
<qdev-path>" command instead of mixing both usages under an info command.
