This change creates the following directories under docs/
in order to provide a grouping for the content:

- components
- design
- getting_started
- perf
- process

In each of these directories an index.rst file is created
and this serves as an index / landing page for each of the
groups when the pages are compiled. Proper layout of the
top-level table of contents relies on this directory/index
structure.

Without this patch it is possible to build the documents
correctly with Sphinx but the output looks messy because
there is no overall hierarchy.

This patch covers two changes:

- Links that refer to GitHub are updated to point to the
  relevant content on trustedfirmware.org

- Internal links between documents have been updated,
  with the required .rst suffix being added or due
  to a change in the relative locations of the files.

With the TF wiki being migrated from GitHub to trustedfirmware.org,
some documents will be moved into the docs/ directory within the
repository rather than remaining as external content. The
appropriate action has been decided on a per-document basis.
