- Implement SPI devices in dts files for all devices - Removed `tt::hal::spi` HAL and its configurations - Fix for devicetree generator "boolean" support - Remove unused custom locks in all `DisplayDevice` implementations - Fixed some bugs with devices - Updated XPT2046 driver - Fix for `WifiEsp` deadlock - Export a lot of new `math.h` symbols with `tt_init.cpp` - Created `SpiDeviceLock` in `TactilityCore` as a wrapper for kernel SPI locking - Improved `TactilityKernel` SPI driver.
