- Cleanup unused code and move ISR/IRQ checks to `Kernel.h`
- Improve clang-format
- Fix for LVGL lock transfer: ensure lock isn't activate when changing the lock
- Implement SPI HAL
- Remove `initHardware` HAL configuration entry

- Show I2C device name in I2C Scanner app
- Register various I2C devices from board implementations
- Fix M5Stack Core2 power status
- Fix pre-allocation issue in `hal::Device`
- Create `Include/` folder for all main projects
- Fix some issues here and there (found while moving things)

- Fix for I2cDevice read/write calls that checked for `esp_err_t` instead of `bool`
- Fix for TinyUSB init that checked for `esp_err_t` instead of `bool`
