MLK-23694-12 arm64: dts: imx8mp-evk: integrate LVDS bridge display in

Integrate LVDS bridge with single channel display into EVK DTB
to support DSI + LVDS dual display, and the previous single
display support for DSI or LVDS is also remained. Put LCDIF1
and LCDIF2 ports into one display-subystem node to implement
this kind of dual display.
