UART6启用dma,可以直接修改rtconfig.h文件，里面增加宏定义RT_SERIAL_USING_DMA BSP_USING_UART6 BSP_UART6_RX_USING_DMA和BSP_UART6_TX_USING_DMA即可
也可以通过修改kconfig文件实现菜单配置。
```c
menuconfig BSP_USING_UART
        bool "Enable UART"
        default y
        select RT_USING_SERIAL
        if BSP_USING_UART
            config BSP_USING_UART1
                bool "Enable UART1"
                default y

config BSP_UART1_RX_USING_DMA
                bool "Enable UART1 RX DMA"
                depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA
                default n

config BSP_UART1_TX_USING_DMA
                bool "Enable UART1 TX DMA"
                depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA
                default n

config BSP_USING_UART2

                default n
