MLK-16158-2 ARM64: dts: imx8mq-evk: add a new dts to support 'LCDIF-->DSI'

There are two independent display path on imx8mq platform:

    a. DCSS  --> HDMI
    b. LCDIF --> DSI

The default enabled display path is 'DCSS-->HDMI', so add
a new dts to enable 'LCDIF-->DSI', and at the same time,
disable 'DCSS-->HDMI' path.
