boards: arm: frdm_k64f: add settings to use WNC-M14A2A LTE-M modem

Browse source 
These settings enable use of the WNC-M14A2A LTE-M modem as the default
network interface instead of ethernet.

They include the following settings when MODEM_WNCM14A2A is selected:
- UART 2 setup
- Avoid ETH_0 setup due to pin conflicts
- DTS addition for WNC-M14A2A
- Kconfig settings for modem driver
