Merge #423

423: nRF9160 support r=Dirbaio a=diondokter

- Created a chip file with all the peripherals, interrupts and peripheral implementations.
- All peripherals now use an alias for the NS (non-secure) version of the nRF9160 version.
- Implementations of peripherals that don't exist are ignored.
- Most PPI functionality has been stubbed out because the nRF91 has the newer DPPI which is not compatible with the current API. (The channels are also set to not configurable, so they are kinda useless now, but in principle the stubs should never be called)
