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.
