This commit adds support for the device in a way that is compatible
with the vendor firmware's bootloader and dual-boot flash layout, the
resulting image can directly be flashed using the vendor firmware.

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.

Use approach suggested by Adrian Schmutzler instead of introducing
another device variable.
Also revert the unnecessary white-space changes accidentally introduced
by the previous commit.

Use dedicated dts folder like on ramips to store device tree source
files for boards not already supported in vanilla Linux.
Doing so instead of having them in files-* has several advantages:
* we don't need to duplicate them for several kernel versions
* changes to a device tree don't trigger a complete kernel rebuild
* the files are more obvious to find
