watchdog: tangox: Set max_hw_heartbeat_ms instead of max_timeout
Setting max_hw_heartbeat_ms lets the watchdog core provide a virtual
timeout if the timeout requested by user space is larger than the maximum
hardware timeout. Also, it helps the watchdog core to provide heartbeats
if the hardware watchdog is running while closed.
