glados: Turn off LEDs in hibernate

Browse Source 
Use new board-level hibernate GPIO state function to turn off LEDs in
hibernate.

BUG=chrome-os-partner:43807
TEST=Manual on Glados with subsequent commit. Run 'hibernate' on console,
verify that LED remains off. Press power button, verify that board wakes.
