    i2c/ww_ring: stop running programs before loading the new ones
    
    The two controllers on the ring are programmed independently, and if
    the second controller is running the old pattern while the first one
    was loaded with a new pattern, there is a window of when the two
    unrelated patterns might interact.
    
    To avoid this shut down execution on both controllers before starting
    downloading the new pattern code.

    BUG=chrome-os-partner:36059
    TEST=verified recovery/wipeout LED ring behavior did not change.
