watchdog: rti_wdt: Set min_hw_heartbeat_ms to accommodate a safety margin
commit cae58516534e110f4a8558d48aa4435e15519121 upstream.
On AM62x, the watchdog is pet before the valid window is open. Fix
min_hw_heartbeat and accommodate a 2% + static offset safety margin.
The static offset accounts for max hardware error.
Remove the hack in the driver which shifts the open window boundary,
since it is no longer necessary due to the fix mentioned above.
