    rk3288: slowly raise to max cpu voltage to prevent overshoot
    
    slowly raise to max cpu voltage to prevent overshoot,
    and in our experience,when cpu run in 1.8GHz,the
    vdd_cpu must up to 1.4V
    
    BUG=chrome-os-partner:32716, chrome-os-partner:31896
    TEST=Boot on veyron_pinky rev2,check the rk808 buck1 voltage 1400mv
         and measure the overshoot is 1440mv
