Crate nrf52dk

Tock kernel for the Nordic Semiconductor nRF52 development kit (DK), a.k.a. the PCA10040.
It is based on nRF52838 SoC (Cortex M4 core with a BLE transceiver) with many exported I/O and peripherals.

nRF52838 has only one port and uses pins 0-31!

Furthermore, there exist another a preview development kit for nRF52840 but it is not supported yet because unfortunately the pin configuration differ from nRF52-DK whereas nRF52840 uses two ports where port 0 has 32 pins and port 1 has 16 pins.
