The SPDX license identifier must be in the first line of a file,
unless there is a shebang (then it's the second line).
Fix this for the local files, do not care about the upstream patches.
While at it, update the identifiers where necessary.

Instead of adding those device tree sources using a patch, simply move
them to the newly created dts folder.
