[PATCH v1] arm64: dts: freescale: imx8mm-verdin: Remove LVDS panel and backlight

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Remove LVDS panel and backlight nodes from the Verdin iMX8M Mini SoM
dtsi file, those two hardware components are not part of the SoM,
therefore they should not be present in this file.

This is solving a dtb checker warning about panel-lvds compatible.
