zbt-wd323: add GPIO WDT support
Watchdog has not been properly configured for this router - the PCB has a
hardware watchdog connected to one of the GPIO pin 21 [1]
This commit provides this fix [2]
Without this fix, the ZBT-WD323 is unusable in OpenWRT because it power
cycles every 30 seconds due to the watchdog tripping
