Disable stack protection explicitly

Explicitly disable stack protection via the "-fno-stack-protector"
compiler option when the ENABLE_STACK_PROTECTOR build option is
set to "none" (the default).

This allows the build to complete without link errors on systems where
stack protection is enabled by default in the compiler.

xlat_table_v2: Fix enable WARMBOOT_ENABLE_DCACHE_EARLY config

The WARMBOOT_ENABLE_DCACHE_EARLY allows caches to be turned on early during
the boot. But the xlat_change_mem_attributes_ctx() API did not do the required
cache maintenance after the mmap tables are modified if
WARMBOOT_ENABLE_DCACHE_EARLY is enabled. This meant that when the caches are turned
off during power down, the tables in memory are accessed as part of cache
maintenance for power down, and the tables are not correct at this point which
results in a data abort.
This patch removes the optimization within xlat_change_mem_attributes_ctx()
when WARMBOOT_ENABLE_DCACHE_EARLY is enabled.

We would need to update this version for the release but, in fact,
it is not required for our publishing workflow; the hosted version
of the docs uses git commit/tag information in place of these
variables anyway.

Instead of updating the version, just remove these variables
entirely.

doc: Formatting fixes for readme.rst

The readme.rst file in the project root is the front-page that
is displayed on Github and if viewing the TF-A repository on
git.trustedfirmware.org in the "about" view. It now contains a
small amount of stub content, and directs readers to the
ReadTheDocs documentation via trustedfirmware.org/docs/tf-a.

The Github renderer is displaying the content fine but the cgit
viewer displays some "backlink" errors because some content
substitutions were left in place (terms surrounded by pipe
symbols), e.g. |TF-A|.

This patch removes those substitutions, that are not supported
by cgit, and also updates one heading to clarify where to find
the new docs.

doc: De-duplicate readme and license files

The readme.rst and license.rst files in the project root overlap
with the index.rst and license.rst files in the docs/ folder. We
need to use the latter when building the documentation, as Sphinx
requires all included files to be under a common root. However,
the files in the root are currently used by the cgit and Github
viewers.

Using symlinks in Git presents some difficulties so the best
course of action is likely to leave these files but in stub form.

The license.rst file in the root will simply tell the reader to
refer to docs/license.rst.

The readme.rst file will contain a small amount of content that
is derived from the docs/index.rst file, so that the Github main
page will have something valid to show, but it will also contain
a link to the full documentation on ReadTheDocs.

doc: Convert internal links to RST format

Currently links between documents are using the format:

<path/to/><filename>.rst

This was required for services like GitHub because they render each
document in isolation - linking to another document is like linking
to any other file, just provide the full path.

However, with the new approach, the .rst files are only the raw
source for the documents. Once the documents have been rendered
the output is now in another format (HTML in our case) and so,
when linking to another document, the link must point to the
rendered version and not the .rst file.

The RST spec provides a few methods for linking between content.
The parent of this patch enabled the automatic creation of anchors
for document titles - we will use these anchors as the targets for
our links. Additional anchors can be added by hand if needed, on
section and sub-section titles, for example.

An example of this new format, for a document with the title
"Firmware Design" is :ref:`Firmware Design`.

One big advantage of this is that anchors are not dependent on
paths. We can then move documents around, even between directories,
without breaking any links between documents. Links will need to be
updated only if the title of a document changes.
