5e2ca8aed4 LR2021 radio on NRF_Promicro (#10401)
* LR2021 radio on NRF_Promicro

Co-authored-by: Copilot <copilot@github.com>

* Refactor LR2021 interface includes and conditional compilation for improved clarity

Co-authored-by: Copilot <copilot@github.com>

* Refactor LR20x0 interface: remove unused includes and update comments for clarity

* Fix LR2021 max power definitions and add radio type detection tests

* remove potato radio type detection tests

* Include placeholder for DCDC - currently requires godmode

* Added godmode features - not enabled by default
