- Add kernel support for SPI driver - Add kernel support for UART driver - Implemented ESP32 UART kernel driver - Update existing UART-related code in Tactility to use new kernel driver - Remove UART from tt::hal::Configuration - Remove tt_hal_uart functionality but keep functions for now - Update devicetrees for UART changes - Kernel mutex and recursive mutex: improved locking API design - Other kernel improvements - Added device_exists_of_type() and device_find_by_name()
