From: Max Krummenacher <max.krummenacher at toradex.com>

The LVDS_DSI_SEL does not leave the SoM, so do its pinmuxing on the SoM dtsi and don't
leave that to a carrier board dts file.

Using a pull down on the LVDS_DSI_SEL signal is enough to have the signal not floating
and have the SoM in a defined state.
Thus remove the gpio-hog used on the line and leave this to carrier board dts files or
overlays to use the signal as needed.
