Some bugfix suggestions for ESP32S3 boards

[gampam2000]

Hi,

In order to get this working for an ESP32S3 board I needed to do the following:

• created an empty main/linker.lf file
• added sdkconfig.idf52 to mpconfigboard.cmake
• run idf.py add-dependency espressif/esp_tinyusb before compilation
• compilation: idf.py build -D NINJA_FLAGS="-j 2"

I also have a question: After compilation I do not get a combined firmware image in the build folder. How or where could I change this, so that also a combined firmware.bin file is created?

Thanks & best regards,
