This patch integrates the watchdog triggering into the recently added cyclic infrastructure. Each watchdog device that shall be triggered registers it's own cyclic function. This way, multiple watchdog devices are still supported, each via a cyclic function with separate trigger intervals.

v1:
- Reword WDT logging at startup as suggested by Rasmus

As a future enhancement, I think the cyclic handlers should return an error code, which is retained somewhere, so it is possible to check (perhaps on cmdline) whether there has been an error since the last check.
