Stash away the option argument with add_device_config(), so we still
have its location when we get around to parsing it.

This doesn't improve any messages I can see just yet, but that'll
change shortly.

The current names don't bother me, but I'd be fine with a rename, too.
Unless I need to respin anyway, I'd rather leave it to a follow-up
patch, though.
