nrf: add support for UICR configuration.

Browse Source 
- APPROTECT enable/disable. Notably this fixes issues with nrf52-rev3 and nrf53 from locking itself at reset.
- Use NFC pins as GPIO.
- Use RESET pin as GPIO.

NFC and RESET pins singletons are made available only when usable as GPIO,
for compile-time checking.
