Leah Rowe cc1642096e Use SPDX license headers on all scripts
This results in much cleaner copyright and license declarations.
SPDX headers are legally recognised and make auditing easier.

Also, remove descriptions of each script, from each script.
Libreboot documentation at docs/maintain/ describes them.
