Config dsi node for mt8183 kukui. Set panel and ports.

Several kukui boards share the same panel property and only compatible
is different. So compatible will be set in board dts for comparison
convenience.

It'd make sense to add also the backlight here?

+               backlight = <&backlight_lcd0>;

I think you should enable the MIPI TX to have DSI and panel working?

+&mipi_tx0 {
+       status = "okay";
+};
