nxp1052 串口bsp驱动，如果应用程序对某个串口重新配置波特率等参数，该串口无法接收数据，需将中断重新使能

应用程序如果重新配置串口参数会调用 `static rt_err_t imxrt_configure(struct rt_serial_device *serial, struct serial_configure *cfg) { struct imxrt_uart *uart; lpuart_config_t config; RT_ASSERT(serial != RT_NULL); RT_ASSERT(cfg != RT_NULL); uart = rt_container_of(serial, struct imxrt_uart, serial); LPUART_GetDefaultConfig(&config); config.baudRate_Bps =...

串口使用POSIX接口 ioctrl 无法设置底层参数，不会调用底层config 由于宏定义的数值为3
