    samus: Set current backlight PWM value
    
    With recent changes in the 3.14 kernel and the switch to not
    using X the panel backlight is not geting turned on until
    chrome is started which means the splash screen is not visible.
    
    If we set the backlight PWM in coreboot then it will at least
    turn on for the early boot process.
    
    BUG=chrome-os-partner:31549
    BRANCH=samus
    TEST=boot on samus in normal mode and see the boot splash logo
