qdev is a leaky layer above QOM.
qdev properties are also QOM properties.
All device properties are exposed externally.
We use device properties for:
* Letting users configure pluggable devices, with -device or device_add
* Letting code configure onboard devices
For onboard devices that are also pluggable, everything exposed to
code is also exposed externally. This might be a mistake in places.
* Letting the machine versioning machinery adjust device configuration
Some properties are meant to be used just for this. They're exposed
externally regardless, which is a mistake.
