mainboard/google/reef: implement phase enforcement pin

On upcoming boards an optional pull up is applied on GPIO_10
    to indicate if the board should have security features locked
    down for a shipping system. Provide a weak pull down so that
    all boards will indicate a logic 0 until the stronger pull up
    resistor is stuffed.
