* Fix Multimodule showing up as Crossfire when only multimode and not crossfire is enabled.
* Don't hardcode telemetry to be Frysky on non STM32 arm targets
* Port multi module code to 9X platforms
* Allow Spektrum telemetry protocol to be selected as protocol for the telemetry selection
* Fix infinite loop in spektrum code

Changes also done for Horus and Taranis UI where appropriate
