rust: faux: add Device type with AsBusDevice support

Browse source

Add a faux::Device type that wraps struct faux_device and implements
AsBusDevice, enabling faux devices to be used as parent devices for
subsystems that require a bus device, such as DRM.

Update Registration to return &faux::Device<Bound> via AsRef.
