That's not that hard, we can remove the initialisation of wdt_timeout to
WDT_DEFAULT_TIMEOUT and use the 0 magic value, which is not an
acceptable timeout value, to tell whether the variable was set with a
module parameter or not.
I followed what was done in the at91sam9_wdt driver but I agree the
module parameter should override the DT property, if we all agree on
that, I will also change this behavior in at91sam9_wdt in v2, at least
for the sake of coherency between drivers.
