Stefan Adolfsson e89486c9b6 npcx: CEC: Write messages on the CEC bus 
Add hooks that ectool or AP will use to send CEC messages.
Messages are sent by setting a timer and flipping
a GPIO in the timer interrupt. The timer is then
recharged in inside that interrupt depending on
where it is in the CEC state-machine.
