I wasn't quite right about this -- turns out that machines can
have a reset method, but it is a weird special case method
MachineClass::reset that isn't like device reset. (We use it
in a few machine types; if implemented, it is responsible for
calling qemu_devices_reset() to kick off device reset. Probably
MachineClass ought to implement TYPE_RESETTABLE_INTERFACE
instead.)
