Intel-SIG: commit 6d72c7ac watchdog: wdat_wdt: Using the existing
function to check parameter timeout

-------------------------------------

If max_hw_heartbeat_ms is provided, the configured maximum timeout is not
limited by it. The limit check in this driver therefore doesn't make much
sense. Similar, the watchdog core ensures that minimum timeout limits are
met if min_hw_heartbeat_ms is set. Using watchdog_timeout_invalid() makes
more sense because it takes this into account.
