2.2 RC1 - RGB LED Strip Control broken on Matek F405SE

[b14ckyy]

Current Behavior

RGB LED Control seems not to work on Matek F405SE (Wing) - LEDs just randomly flashing or flickering.

Steps to Reproduce

1. Setup RGB LEDs on a F405SE Wing with INAV 2.2 RC1

2. Power on board

3. if some LEDs will power up at all (depends on the LEDs) they will randomly shining or flickering

4. all fine when flashing back to 2.1

5. same with scratch setup LEDs or restoring LED settings from 2.1

Expected behavior

LED control behavior should be the same as in 2.1?

Suggested solution(s)

Check for LED control output on Matek F405SE Wing

Additional context

Tested and confirmed this with 2 flight controllers and 2 known good sets of RGB LEDs.
