eve: Disable PMIC power button shutdown timer
Disable the PMIC shutdown timer for power button to prevent
it from being able to shutdown the system. Refresh+Power is
still the best way to do a PMIC reset.
BUG=none
TESET=manual: Close lid and enter suspend, hold power button for
>30 seconds and ensure EC stays up and system stays in suspend.
