    libfdt: overlay: Report a bad overlay for mismatching local fixups
    
    The __local_fixups__ node as a structure that mimics the structure of the
    main overlay part.
    
    This means that if we have a child node somewhere in the local fixups
    sub-tree and if that node is not present in the main tree, the overlay is
    poorly formatted, and we should report it as such.
