- Introduced new HAL components for LCD and MIPI DSI, including: - `lcd_hal.c` and `lcd_hal.h` for LCD hardware abstraction layer. - `mipi_dsi_hal.c` and `mipi_dsi_hal.h` for MIPI DSI hardware abstraction layer. - Peripheral connection definitions in `lcd_periph.c` and `lcd_periph.h`. - Added necessary types and utility functions in `lcd_types.h` and `mipi_dsi_types.h`. - Updated CMakeLists to include the new HAL components in the build system. - Removed legacy references to LCD and MIPI DSI in the HAL and SOC CMakeLists.
