watchdog: imgpdc: Allow timeout to be set in device-tree
Since the heartbeat is statically initialized to its default value, watchdog_init_timeout() will never look in the device-tree for a timeout-sec value. Instead of statically initializing heartbeat, fall back to the default timeout value if watchdog_init_timeout() fails.
