From: Philippe Mathieu-Daudé <f4...@amsat.org>
The MachineClass uses an inverted logic (inherited from the
PC machines [*]) to create the chardev backends for the default
devices (see commits 998bbd74b9d..aa40fc9c964 and ac33f8fad14).
As the none-machine doesn't have any hardware device, it is
pointless to initialize chardev backends. Fix by setting the
'no_defaults' bits in its MachineClass.
