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 it uses different
io to control backlight, it will hard to distinguish it. So, we
move the backlight control to mainboard, and use board_id
to distinguish the backlight control.
BUG=None
TEST=emerge veyron_pinky and Boot the pinky board
BRANCH=None
