  n1sdp: update platform macros for dual-chip setup
  n1sdp: introduce platform information SDS region

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link  for now only dual-chip is
supported.

A single instance of TF-A runs on master chip which should be aware of
slave chip's CPU and memory topology.

This patch updates platform macros to include remote chip's information
and also ensures that a single version of firmware works for both single
and dual-chip setup.

Platform information structure holds information about platform's DDR
size(local/remote) which will be used to zero out the memory before
enabling the ECC capability as well as information about multichip
setup. Multichip and remote DDR information can only be probed in SCP,
SDS region will be used by TF-A to get this information at boot up.

This patch introduces a new SDS to store platform information, which is
populated dynamically by SCP Firmware.previously used mem_info SDS is
also made part of this structure itself.

The platform information is also passed to BL33 by copying it to Non-
Secure SRAM.

Running TF-A from non-standard location such as DRAM is useful for some

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.

The list of upstream platforms on the index page is growing
quite long, especially with all the FVP variants being listed
individually.

This patch leverages the "Platform Ports" chapter in the docs
table of contents to condense this information. Almost all
platform ports now have documentation, so the table of
contents serves as the list of upstream platforms by itself.

For those upstream platforms that do not have corresponding
documentation, the top-level "Platform Ports" page mentions
them individually. It also mentions each Arm FVP, just as
the index page did before.

Note that there is an in-progress patch that creates new
platform port documentation for the Arm Juno and Arm FVP
platforms, so this list of "other platforms" will soon be
reduced further as those platforms become part of the
table of contents as well.

The index.rst page is now the primary landing page for the TF-A
documentation. It contains quite a lot of content these days,
including:

- The project purpose and general intro
- A list of functionality
- A list of planned functionality
- A list of supported platforms
- "Getting started" links to other documents
- Contact information for raising issues

This patch creates an "About" chapter in the table
of contents and moves some content there. In order,
the above listed content:

- Stayed where it is. This is the right place for it.
- Moved to About->Features
- Moved to About->Features (in subsection)
- Stayed where it is. Moved in a later patch.
- Was expanded in-place
- Moved to About->Contact

There are some platforms which uses MPIDR Affinity level 3 for storing
extra affinity information e.g. N1SDP uses it for keeping chip id in a
multichip setup, for such platforms MPIDR validation should not fail.

This patch adds Aff3 bits also as part of mpidr validation mask, for
platforms which does not uses Aff3 will not have any impact as these
bits will be all zeros.

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.

The version of the Linaro release that is used for testing was
updated in 35010bb8

 and the user guide was updated with the
correct version, however the version is also mentioned on the
index page and that was missed. Update the index page with the
new version.

We can come back and de-duplicate this content later, to ease
future maintenance.

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.
