Pull Request Overview

This PR adds adaptation support for the Raspberry Pi RP2350 microcontroller by creating a new BSP (Board Support Package). The RP2350 is a newer dual-core ARM Cortex-M33 microcontroller from Raspberry Pi with enhanced security features.

• New BSP implementation for raspberry-rp2350 based on existing raspberry-pico BSP
• Driver support for common peripherals including UART, GPIO, SPI, I2C, PWM, ADC, WDT, and RTC
• LVGL support for LCD display functionality
• Arduino compatibility layer for easier migration

• The macro name 'BSP_S_SPI_MOSI_PIN' should be 'BSP_S_SPI1_MOSI_PIN' to match the pattern used in other SPI1 pin definitions.

        .mosi = BSP_S_SPI_MOSI_PIN,                        \
