drivers: modem_cellular: add nRF91 series (w/ SLM)
The nRF91 series devices, when running the Serial LTE Modem (SLM) application starting with nRF Connect SDK 2.6.0, can now be used as standalone modems via the generic modem_cellular driver. A configuration to run the cellular_modem sample on the nRF9160 DK (plugged in to another nRF91 series device running SLM) is provided.
