[PATCH v3 0/2] use SPDX also for GFDL documents

There are 438 document files that were licensed under the
free versions of GNU Free Document License.

The free versions are the one that doesn't contain invariant
parts.

The first patch adds the license files.  As newer documents
aren't supposed to use them without being dual-licensed
with GPLv2, add them under LICENSE/deprecated.

The second patch replaces a boilerplate text from 
ring-buffer-design.rst by the corresponding SPDX header.

The other documents are all under Documentation/uapi/media.

A separate patchset, to be merged via the linux-media tree
will cover those.
