driver: wdt: npcx: Remove watchdog reset waiting loop in ISR

Browse source 
NPCX watchdog driver has a WDT_NPCX_DELAY_CYCLES for delay the watchdog
reset time after the watchdog timeout. For some systems, users would
like to use the watchdog timeout ISR but don't reset the chip
immediately. Let the system have the final chance to ongoing the system
before the real hardware reset time. Removing the watchdog reset
waiting loop in ISR lets users decide whether wait for watchdog reset
by themself.
