Mauro Carvalho Chehab 059b1c5b15 media: docs: use the new SPDX header for GFDL-1.1 on *.rst files
SPDX v3.10 gained support for GFDL-1.1 with no invariant sections:

	https://spdx.org/licenses/GFDL-1.1-no-invariants-or-later.html

So, remove the license text, replacing them by this new SPDX
license.
