This patch changes the default behaviour of the imx watchdog. Without
the patch: If the system boot with watchdog enabled (by the bootloader),
the driver sets up a threads to pet the watchdog. With the patch,
imx2_wdt_ping() is called once during probe but the thread is not
started. There are no timeout or early_timeout paremters in the DT or in
the kernel command line.

I don't like the old behaviour, but I think there are some setups that
rely on this feature.
