Program the max_hw_heartbeat_ms value so that the watchdog_pretimeout
worker is activated. This kernel worker thread makes sure to ping the
watchdog in case the userspace is unable to do so. This kernel worker
ping will be done only till the full watchdog timeout there by
maintaining the watchdog functionality in case of a real hang.
