No, it doesn't. First of all we are very early here, so we might not even
see the crash. Then, with devicetree probing we may often end up with
the same devices registered from the devicetree and from the
platform/soc. While this should find a way to avoid duplicate device
registration, it is not nice having barebox crash in this case.
