Subject: [PATCH v1 1/2] arm64: dts: freescale: imx8mp-toradex-smarc: fix lvds dsi mux gpio

From: Max Krummenacher <max.krummenacher@...adex.com>

The MUX which either outputs DSI or 2nd channel LVDS signals is part of
the SoM. Move the pinmuxing of the GPIO used for controlling the MUX
to the SoM dtsi file.
