mcu/nrf: Increase watchdog interrupt priority
Watchdog interrupt priority was set to minimal value.
It seems that when Watchdog interrupt is triggered there is
no much that can be done and the system reboot is imminent,
so there is not point in doing anything else while watchdog
interrupt handler can indicate problem.
If some other interrupt had problem that resulted in busy loop
watchdog interrupt would never fire due to lowest priority set.
This increases watchdog interrupt priority to maximum for
Nordic MCU's.
