Some devices can monitor the CEC pin using an interrupt, but you only want to enable the interrupt if you actually switch to pin monitoring mode. So add a new op that is called when pin monitoring needs to be switched on or off. Also fix a small bug where the initial CEC pin event was sent again when calling S_MODE twice with the same CEC_MODE_MONITOR_PIN mode.
