    rockchip: kevin/gru: Slow memory down to 300 MHz
    
    At the higher speeds stressapptest shows memory errors.  We don't want
    to track down random problems due to simple memory corruption, so slow
    memory back down to 300 MHz until someone figures out how to make it
    faster without sacrificing reliability.
    
    BRANCH=None
    BUG=chrome-os-partner:54144
    TEST=stressapptest -M 1024 -s 240
