Enable the GPIO reset pin feature of nrf52840_pca10090
on pin P1.02 and the wait NOP feature of the controller.
These are used to let nrf9160_pca10090 synchronize the
HCI communication with nrf52840_pca10090 controllers.

Add a project configuration for nrf52840_pca10090 that will
route the nRF9160 interface pins to the nRF52840, and use them
for HCI over UART.
