mass-import: Import dokuwiki pages to rst

[gastmaier]

PR Description

Import the pages under /linux-drivers/ at https://wiki.analog.com.

The import had 3 stages:

• step0: fetch artifacts from dokuwiki to wiki, with grep /linux-drivers/ to wiki/ folder
• step1: for wiki/* convert to rst with pandoc at rst/ folder
• step2: copy to docs, build and interactively

Step 1 used the approach

• pre-patch dokuwiki files: many wiki-roles were broken, many pages with many broken syntax.
  converted, with a lot of regex, to formats that are better parsable later on.
  There are 8 different "git-wiki-role" to create link roles.
• pandoc convert to rst
• pre-patch rst files: here we solve (cross-)references, and roles we
  propagated from the pre-patch dokuwiki, we resolve.

Step 2:

• Build the docs, solve the warnings.
• At the beginning, the fixes are made in the wiki/ files, and
  step1+step2 is run again (adoc serve catches the changes, rebuilds)
• After the # of warnings are manageble and are things that really broken,
  I started to fix on the .rst files (not running step1 anymore), until reaching the final stage.

Unresolved issues are marked with the .. todo:: directive.
