The same change as was done for zynqmp with this description:
Add support for enabling the first watchdog pointed via aliases.
DT fragment: aliases { ... watchdog0= &watchdog0; watchdog1 = &watchdog_lpd; ... };
<zynqmp example removed>
Till this patch the first watchdog found in DT was used and started which is not enabling all possible configuration based on user request.
