461: nrf: add initial nrf5340 support r=Dirbaio a=Dirbaio

Thanks to `@diondokter's` work on DPPI this was quite easy! :) 

TODO:
- [ ] Add config option to enable 128mhz
- [ ] Add config option to unlock APPROTECT automatically.
- [ ] Add a way to boot net (config option or API?)
- [ ] Support WDT (there's WDT0, WDT1. Needs some refactor)
- [ ] Support NVMC
- [ ] Support TEMP
