Add support for nrf52840_pca10090, i.e. the nRF52840 SoC on the
pca10090 development kit. The SoC is tasked to route some of the
nRF9160 pins to different components on the development kit.
Additionally, it can be used as a Bluetooth HCI device.
The routing options appear under "Board config" in Kconfig.
