* SDMMC frequency selection based on board type
On Olimex ESP32 EVB I/O operations with SD card can cause error when LAN is used in same time.
Problem is disappearing if SD MMC frequency lower down from SDMMC_FREQ_HIGHSPEED to SDMMC_FREQ_DEFAULT.
No problem if WiFi used instead LAN.
* Code rewritten according to https://github.com/espressif/arduino-esp32/pull/5688#pullrequestreview-759359645
## Summary
Adds support for the new ATMegaZero ESP32-S2 board. Adds the relevant section to `boards.txt` and adds the folder for the `atmegazero-esp32s2` with the proper `pins_arduino.h` to the `variants` folder.
## Impact
Allows users to compile code properly for the ATMegaZero ESP32-S2 without having to use a similar board and manually entering pin numbers.

Thanks!
* The board.txt has been updated. Added variant folder.
Necessary additions for deneyapMiniKart were made in board.txt. Added pins_arduino to variant folder. deneyapMiniKart information has been added.
* Added variant files and added text in board.txt

* Add initial support for USB MSC
* Add Firmware Upload/Download With MSC
Current running firmware is available as file inside the MSC Disk. To update the firmware on the ESP, just copy a regular firmware bin into the drive
* Support overwriting of the firmware file
Overwriting a file is done totally differently on MacOS, Windows and Linux. This change supports it on all of them.
* Allow CDC, FirmwareMSC and DFU to be enabled on boot
* Add example ESP32-S2 USB-ONLY board
* Various device code optimizations
Added `end()` methods to MSC classes
Made begin() methods safe to be called multiple times
Optimized CDC class
* Fix CDC Connect/Disconnect detection in Arduino IDE on Windows
* Rework cdc_write
* Update ESP32-S2 board configs
Add support for the Trueverit Universal IoT Driver MK II (https://www.trueverit.com)
The board will be released on market using electronic distributors soon, as the other one board added via #5219
This new board (referred as MK II) has onboard Texas Instruments DP83848 Eth PHY chip.
The doitESPduino32/pins_Arduino.h lacks definitions for the common SPI pins names: SS, MOSI, MISO, SCK
This breaks compatibility with Arduino libs, including SPI.h/.cpp
This PR solves the issue while maintaining compatibility with previous pin naming (IO5/23/19/18), and ensures consistency with other boards variants.
done on behalf of @ladyada, this PR does:
Add Adafruit FunHouse and upcoming Adafruit Feather Esp32s2
Update Adafruit magtag and metro esp32s2 to have tinyuf2 as factory app
Also modify platform.txt as discussed in adafruit#2 + adafruit#3 + adafruit#4 to add support for
Board/variant partition.csv, bootloader.bin ( priority is user sketch > variant > build.parition/boot )
upload.extra_flags to optionally flash tinyuf2 as factory application
Remove duplicated parameter in running python script in linux and windows
Please review and let me know if you want any changes.
Notes: tinyuf2 is a uf2 bootloader for multiple platforms. For esp32s2, it is an factory app to perform uf2 firmware update.
* Update pins_arduino.h
Fix the bug that the IDE show: "Error compiling for the board FireBettle-ESP32"
Detial"error : redefinition of const uint8_t D0~D9"
* Update pins_arduino.h

Add the Wemos Lolin32 Lite (no longer being produced same as Lolin32) and
the TTGO T7 v1.3 and v1.4 boards (status unknown). All three are rather
generic ESP32 boards the main difference being pin layouts.
