…函数内添加串口3的引脚初始化代码

拉取/合并请求描述：(PR description)

为什么提交这份PR (why to submit this PR)

在 FRDM-MCXA366 开发板上，串口3（UART3）的引脚尚未初始化，导致该串口无法正常使用。本次提交补充了 UART3 的引脚初始化代码，使开发者可以直接使用 uart3 设备进行调试或通信。

你的解决方案是什么 (what is your solution)

在 bsp\nxp\mcx\mcxa\frdm-mcxa366\board\MCUX_Config\board\pin_mux.c 的 BOARD_InitPins() 函数内，增加了 UART3 的 TX和 RX引脚的功能配置，调用 MCXA366 的 库函数进行初始化。同时确保该配置仅在 #define BSP_USING_UART3 宏启用时生效。

请提供验证的bsp和config (provide the config and bsp)

  • BSP: bsp/nxp/frdm-mcxa366

  • .config: CONFIG_BSP_USING_UART3=y

A366原本的调式的串口是可以用的，你这边说的串口三是做什么作用？
