This error code has not been upstreamed and is not really needed since it
is unlikely to be triggered. Drop it to maintain compatability with
upstream.

These header files are actually part of libfdt. Move them there to make
it easier to build pylibfdt and easier to merge changes from upstream.
Update the license header to use SPDX at the same time.
