[PATCH v1 20/25] arm64: dts: colibri-imx8x: Move gpio-keys to som level

Philippe Schenker dev at pschenker.ch

From: Philippe Schenker <philippe.schenker at toradex.com>

SODIMM_45 that is connected to "&lsio_gpio3 10" is defined in the
Colibri standard to be a wakeup pin.
Move this to the SoM level device-tree and keep it disabled by default
but do enable it again on the carrier-board.
