Allow LR1121 single RF path (#2998)
* Remove Dual Band option from hardware with only a single LR1121
* Allow LR1121 devices to define only a single RF path
* Extract common code to a function
Also check the supported rate in the SetRFLinkRate and bail early if not supported
* move isSupportedRFRate() after change via sync pkt...
SetRFLinkRate() is now set correctly with the current rate and the initial frequency configured.
* check allowed rf modes in display menu
* extra check to catch freshly flashed modules with default config
config.GetRate() can return a disabled rf mode, which will get set on uartconnected.
