commit f7c529e00ae58cc9cf78b03aa11894983e8936bc

    veyron: move backlight gpio control to mainboard.c
    
    we use the devicetree to pass the backlight control gpio before,
    but if there have different board version, and use different
    io to control backlight, it will hard to distinguish it. so we
    move the backlight control to mainboard, and we can through board_id
    to distinguish the backlight control.
    
    BUG=None
    TEST=emerge veyron_pinky and Boot the pinky board
    BRANCH=None
