MLK-17117: arm64: dts: fsl-imx8mq-evk: Add support for dual-display

Add a DTS file which will have both the lcdif and dcss nodes enabled and
configured.
The DCSS will work with HDMI output, while the eLCDIF will work with
ADV7535 DSI-HDMI converter.
Also, remove lcdif-rm67191.dts from Makefile, since lcdif is limited to
720p. This combination is no longer working, until we have the timings
for 720p for the MIPI panel.
