arm64: dts: imx8qxp-mek: Add JDI WUXGA LVDS panel support

The JDI TX26D202VM0BWA WUXGA LVDS panel works in LVDS
dual channel mode.  It can connect with the i.MX8QXP
MEK board via J1(for LVDS0) and J3(for LVDS1) jacks.
Either LVDS0 or LVDS1 can be the primary channel.
The panel uses PWM signal supplied by i.MX8QXP to
control the backlight.  This patch adds the panel
support on the i.MX8QXP MEK platform.
