arm64: dts: freescale: imx8mp-toradex-smarc: remove gpio hog

Remove the gpio hog node which forces using DSI signals rather than
the second LVDS channels signals.
The dsi signals are not used in any of the current device trees.
Leave that decision to the actual device tree which will also define
the consumer of the signals.
