watchdog: omap: use watchdog_init_timeout instead of open coding it Instead of (partly) open coding watchdog_init_timeout to determine the inital timeout use the core function that exists for exactly this purpose. As a side effect the "timeout-sec" device-tree property is recognized now (though currently unused in the omap device trees).
