Nathan Binkert e067bc751b Change order of serialization
sim/sim_object.cc:
    serialize objects in the reverse order of their creation.
    This causes a SimObject that is dependent on another
    to be serialized first.  For example, the ethernet device
    writes back some data to physical memory while serializing,
    so this will cause the physical memory to be serialized
    after that, preserving the data written back.
