Commit5d7a95f499("imx6ul/imx6ull: synchronise device trees with linux") removed the display timings from the board device tree whereas they are still needed by the mxsfb driver. Add the timings back (the correct ones) in the imx6ul-opos6uldev-u-boot.dtsi file and remove them from the opos6uldev.env file. Update the opos6uldev_defconfig file so that the LCD turns on at boot.
