MLK-17275-11: dts: imx8qxp-lpddr4: Enable IT6263 and ADV7535
Final step for the OF_DYNAMIC support: enable the LVDS and MIPI-DSI to
HDMI converter nodes by default in the main DTS file for each platform.
This patch enables these nodes for i.MX8QXP LPDDR4 board.
Also, use adi,dsi-channel = <1> for ADV7535, since the panel can only work
on channel 0. By using channel 1 for ADV7535, we can have them work
simultaneously: one on DSI0 and the other on DSI1.
