Backport patches for Kontron i.MX6UL/ULL devicetrees
The purpose of this MR is similar to !43 (merged) for i.MX8MM. It syncs the devicetrees for the Kontron i.MX6UL/ULL boards with the upstream kernel.
This includes renaming the devicetrees to match the actual product names. This will make maintenance easier in the future.
