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* Faulty/outdated RF switching logic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.
A couple of issues was found:
* Wrong CPE patches in RF settings
* Wrong whitening init value for the CMD_BLE5_ADV_NC command
* BLE MAC address was not copied to RAM before set in the bleAdvPar
construct.
* BLE advertisements were not transmitted in intervals as specified by
BLE spec.
With the exception of one specific build configuration for platform nrf52dk, all our arm-based platforms use the debugging I/O library from os/lib/dbg-io. This commit changes the build system to include this module by default for all arm devices. Platform / CPU Makefiles will no longer need to request this MODULE explicitly. Configuration provided to allow exclusion where required, as is the case for nrf52dk when NRF52_USE_RTT is set to 1.
