arm64: dts: colibri-imx8x: Add analogue inputs
This commit does forward-port the ADC functionality from
toradex_5.4-2.3.x-imx.
Upstream-Status: Pending
ADC support seems to be available in mainline, "nxp,imx8qxp-adc"
compatible and node defined in "imx8-ss-dma.dtsi". However it was not
possible to have it working on mainline so we postponed this for the
moment.
