Given the patch 2, when an interrupt is provided by the dt, then the
behavior of the watchdog changes. So we can't do it for all the
platform.
As you propose on your cover letter it is better to set it at board

So instead of this patch you should update the binding documentation
with this new resources. Thanks to this each board developer will be
able to decide to use this feature or not.
Thanks,
Gregory
