Seems to work with serial passthrough without issues, at least on the L3R PRO.
* Fix softserial DMA on stdlcd F4 targets

* More precise soft-serial
* Fix MPM update using inverters & HW uart
* Raise S.PORT DMA/USART IRQ prio to achieve faster switching to input
* Remove useless delays
* Fix flashing external ELRS module
* Added a retry mechanism for FrSky S.PORT update
* Remove useless enableRx()
* External FrSky modules are all flashed via S.PORT
* Remove power management unit update
This was only used on the first batch of X-lite.
* Show true unscaled and unfiltered analogs for diagnose purpose on the analog diagnose screen.
Tested on physical RM TX16S, not yet tested on B/W targets.
* Changed to decimal display also on B/W targets. Tested now with RM Zorro as well.
* 5 fps refresh rate of the raw analog values. Much nicer to look at.
* Time-changing 3 views for color radios: std., filtered raw with deviation, unfiltered raw.
* Corrected deviation view output to not use old values.
* Changed analogs diagnose page to user navigatable TabsGroup with 3 tabs.
* Added fourth analog diagnose tab to show minimum and maximum values and the range (difference between min and max).
Left touch screen and IMU output tests only on first page (should also move in the future to their respective dedicated pages).
* Use Std. JitterAlpha filtering for Deviation screen to minimize delay, omit filtering for FlySky digital hall gimbals - not necessary, the signal is stable enough.
* 2 analog diagnose pages for 128x64 B/W radios: calibrated analogs and raw values with display output limited to 5 frames-per-second due to visibility reasons.
* Added 2 analogs diagnose pages also for 212x64 display B/W radios.
I was only able to simulate it, not tested on real hardware.
* Support also radios that do not have PageUp/PageDn keys, but only Page key (e.g. X7).
* Better key handling and improved style thx to @pfeerick
Added special UART4 init to sample if FlySky sticks are present or not.
Added boolean globalData.flyskygimbals to save the detection result.
Removed FLYSKY_HALL_STICKS and FLYSKY_HALL_STICKS_REVERSE CMake build options.
Tested on two RM TX16S radios, one with FlySky digital hall sticks and second with stock analog sticks.
Before write access is permitted to numerous DMA registers, need to make sure that DMA is disabled for the stream. Disabling the stream is not instantaneous, and needs to be waited for (previous transmissions need to be finished first).
Added return values to numerous functions to signal a failure.
