watchdog: wdat_wdt: Add timeout value as a param in ping method 



According to the WDAT spec that states about WATCHDOG_ACTION_SET_COUNTDOWN_PERIOD:
"This action is required if WATCHDOG_ACTION_RESET does not explicitly write a new
countdown value to a register during a reset."
And that implies, WATCHDOG_ACTION_RESET may write a countdown value, thus may come
with a WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN, thus need the timeout value as parameter
or would otherwise write 0.
The watchdog for SIONCT6126 need a entry WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN for
WATCHDOG_ACTION_RESET action, I send this patch to support it.
