Feature/add esp32s2

[TDA-2030]

Changes

Added support for ESP32S2

There can be little doubt that supporting ESP32S2 is exciting, which allows all of us to DIY at a lower cost. Although the porting work has not been completed yet, you can get the same fantastic experience as STM32 in some functions. I try my best to reduce the modification of openffb code and keep the original code of STM32.

The porting status of functions are as follows:

Main classes

• [x] FFBWHEEL
• MIDI (Not support in this PR)
• TMCDEBUG (Not support in this PR, I don't have TMC driver board)
• CANBRIDGE (Not support in this PR, I don't know what this function does or how to test it)

Extra features

• [x] LOCALBUTTONS (not tested)
• SPIBUTTONS (Not support in this PR, I don't know how to test)
• SHIFTERBUTTONS (Not support in this PR, I don't know how to test)
• [x] ANALOGAXES
• [x] LOCALENCODER
• [x] TMC4671DRIVER(not tested, I don't have TMC driver board)
• [x] PWMDRIVER
• [x] VESC
• [x] CANBUS
• MTENCODERSPI
• CANBUTTONS
• CANANALOG
• ADS111XANALOG
• UARTCOMMANDS

@Ultrawipf PTAL Do you think it's better to merge or separate into another branch?

[Ultrawipf]

I would like to get some hardware to test this myself before merging into the main project so i can make sure support is kept. Really interesting to see this being ported on other chips. Could you supply me with a board or is there a devkit i could buy somewhere with all required ports? Otherwise i will make one from your files. You can contact me via the mail address on my profile or the linked discord.

Sorry for my late reply! I am in China and under the COVID-19 lockdown. It is more convenient for you to make a PCB yourself. Please see the v1.1 version hardware.

In addition, If you have an ESP32-S2-DevKitC-1 or ESP32-S2-Saola-1 development board, you can use it for most of your testing
