    nexus: Add device_shutdown where missing
    
    At shutdown devices may need to do extra work to clean up state, etc.
    This is done in a device_shutdown kobj method on a driver, with the
    default being a `do nothing` method.  Only x86's nexus driver includes
    the device_shutdown method to propagate down to its children, so on
    other architectures the device_shutdown stops at the root, and thus
    device_shutdown is never called for any real devices.  Add this missing
    method to the nexus drivers of the other architectures so devices have a
    chance to properly shutdown.
