    google/chell: Turn on keyboard backlight in romstage
    
    Use the keyboard backlight to provide indication that the system is
    booting.  This is useful for determining that a system is in S0 and
    is running BIOS code.
    
    BUG=chrome-os-partner:47435
    BRANCH=none
    TEST=boot on chell and see keyboard backlight come on early
