This PR adds optional nRF52 hardware watchdog support for repeaters. It could be similarly extended to room servers, etc.
I saw a few other WDT implementations but decided to roll my own that was more configurable and testable.
NRF52Board: configure/feed the SoC WDT, expose reset reason on all nRF52 boards (not onlyNRF52_POWER_MANAGEMENTbuilds)wdt_en(default on),wdt_timeout(default 30 s)watchdog,watchdog on/off,watchdog timeout,watchdog status,watchdog lockup(bench test)board.loop()WDT pauses in sleep/halt per Nordic defaults.
