zephyr: Adjust watchdog warning timer value and delay time
Adjusts the watchdog warning timer value and its delay time definitions
to meet original chromium ec behavior. The system handles the warning
event at CONFIG_AUX_TIMER_PERIOD_MS & issues the watchdog reset event
at CONFIG_WATCHDOG_PERIOD_MS.
Zephyr NPCX watchdog provides a config WDT_NPCX_DELAY_CYCLES for
watchdog timeout delay. Set the zephyr timeout to
CONFIG_AUX_TIMER_PERIOD_MS as warning time. So the NPCX watchdog
hardware issue reset event at CONFIG_AUX_TIMER_PERIOD_MS +
WDT_NPCX_DELAY_CYCLES.
