This patch integrates the main function responsible for calling all registered cyclic functions cyclic_run() into the common WATCHDOG_RESET macro. This guarantees that cyclic_run() is executed very often, which is necessary for the cyclic functions to get scheduled and executed at their configured periods.
If CONFIG_WATCHDOG is not enabled, only cyclic_run() without calling watchdog_reset(). This guarantees that the cyclic functionality does not rely on CONFIG_WATCHDOG being enabled.
