I am not sure if it would be useful. We know that libfdt is not
protected against rogue device-tree and therefore fuzzing will likely
break it. Any device-tree used are expected to be trusted (this is
documented in the tools).
Anyway, it would be nice to get libfdt fixed and provide patch the
upstream version [1].
