The schematics shows the GKTW70SDAD1SD panel in the J4 connector, not
the LVDS J7 connector.

As I mentioned earlier you should remove the display timings from the
dts when using the compatible string for the panel.

power-supply = <&reg_touch_3v3> is not correct, as the reg_touch_3v3
does not power the LCD.

Another hint is to use the PLL5_VIDEO as the clock source for the
lcdif controller as done in the imx6ul evk dtsi.

It would also help if you could share the complete boot log.
