Nitpicking: If you by any chance need to re-send this patch again,
please remove WDT_DEFAULT_TIMEOUT completely from this file.

This is left in order to have some traces of what firmware default is in use.
I can convert this into comment.

Sure. You also could remove it and use this original default
value either via Kconfig (CONFIG_WATCHDOG_TIMEOUT_MSECS) or via
DT ("timeout-sec" property). All is fine with me.
