Some of the plantuml diagrams in the I/O storage abstraction layer
documentation are absent from the rendered version of the porting
guide. The build log (see [1] for example) reports a syntax error in
these files. This is due to the usage of the 'order' keyword on the
participants list, which does not seem to be supported by the version
of plantuml installed on the ReadTheDocs server.

Fix these syntax errors by removing the 'order' keyword altogether. We
simply rely on the participants being declared in the desired order,
which will be the order of display, according to the plantuml
documentation.

Currently we have some pre-rendered versions of certain diagrams
in SVG format. These diagrams have corresponding PlantUML source
that can be rendered automatically as part of the documentation
build, removing the need for any intermediate files.

This patch adds the Sphinx "plantuml" extension, replaces
references to the pre-rendered SVG files within the documents,
and finally removes the SVG files and helper script.

New requirements for building the docs are the
"sphinxcontrib-plantuml" Python module (added to the pip
requirements.txt file) and the Graphviz package (provides the
"dot" binary) which is in the Ubuntu package repositories.

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.

This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

Add the essentials for supporting a Sphinx documentation build:

- A makefile under docs/ to invoke Sphinx with the desired output
  format
- A Sphinx master configuration file (conf.py)
- A single, top-level index page (index.rst)
- The TF.org logo that is integrated in the the sidebar of the
  rendered output
