colibri_imx6: synchronise device tree with linux

Synchronise device tree with linux-next next-20220708.

Please note that this also means that instead of the previous "generic"
U-Boot specific carrier board agnostic device tree we are now using the
regular one for the Colibri Evaluation (carrier) board V3 (e.g.
imx6dl-colibri-eval-v3.dtb rather than the previous imx6-colibri.dtb).
