Two issues caused the sensitivity on CC13xx devices to be dramatically
worse than CC26xx devices:
* Wrong front-end mode configuration
* Faulty/outdated RF switching logic
Both issues are inherently board-specific. Therefore, a generic
configuration was aligned across all boards which allows a specific
board to configure a correct RF front-end mode. In addition, the RF
switching logic was updated to latest and greatest.
