CMake error when when trying to change FEM and coded PHY settings for BT Mesh (Light and Light_Switch example)

[David_Goot]

So when changing the hci_icp.conf settings to have the configuration below, i get "CMake Error at C:/ncs/v2.6.1/zephyr/cmake/modules/kconfig.cmake:358 (message):" plus the warnings for said configuration settings. Using the nordic nRF5340-DK, with v2.6.1 SDK. the only modification we've made to the example code is to have Light_Switch blink continusouly without the push of a button so that we can do range testing without needing someone standing with the light_switch.
