MLK-16973-10 arm64: dts: fsl-imx8qm-mek: Add JDI WUXGA LVDS panel support on LVDS1

This patch adds JDI WUXGA LVDS panel(on LVDS1) support
for the i.MX8QM MEK platform.
Note that the i.MX8QM MEK board needs a hardware rework
to add a 0ohm resistor for R211 to make the PWM backlight
work for the panel.
