stm32l: supports fake-hibernate
We don't have available GPIO pin for power button as the hibernate
(stand-by) wake-up source. Also, we don't want to do board change.
So, put the EC in a decent infinite loop to pretend the hibernate mode
and wait for particular wake-up event. This should be fine because
the AP is already down before EC hibernates.
