Fix PDF builds on media documentation

This series address a series of errors during PDF generation from media documentation.

It replaces the previous patch series entitled:
[PATCH RFC 0/4] Fix PDF build errors

The first patch fixes the late redefinition of a LaTeX command at the Sphinx LaTeX style that causes build to break when some cross-references are used.

The next two patches fix PDF output issues with subdev-formats.rst.

The next 3 patches fix image includes and their output for PDF.

It is aligned with Linus request of not having binary-generated images from their PNG or SVG source codes.

I still intend to move the remaing PNG images to vectorial ones (SVG), as image scale works better, but this will require some additional work. When done, I'll submit as a separate patch series.

It should also be noticed that the last patch violates the output dir, when make is used with "O=some_dir", as Sphinx doesn't accept image files outside the source directory. We'll likely need some Sphinx extension in order to fix it, but at least with this series (plus Jani Nikola's PDF fix series), the PDF output should work fine again.
