Subject: [PATCH v2 24/79] docs: pcmcia: convert docs to ReST and rename to *.rst
Convert the pcmcia docs to ReST format. Most of the changes here
are trivial.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
