boards: arm: nrf52840_pca10056: add settings for WNC-M14A2A modem

Browse source 
These settings enable use of the WNC-M14A2A LTE-M modem as the default
network interface for the nRF52840-DK board (nrf52840_pca10056).

They include the following settings when MODEM_WNCM14A2A is selected:
- UARTE1 pin setup
- DTS / DTS fixup additions for WNC-M14A2A
- Kconfig settings for modem driver
