If DA9063 PMIC is left enabled during suspend, PMIC's watchdog needs to be disabled before entering suspended state to allow board to sleep for longer period than the watchdog timeout period. Otherwise board will be reset by the watchdog. Thus disable watchdog on suspend and re-enable it upon resume.
