Workaround for Neoverse N1 erratum 1868343

Neoverse N1 erratum 1868343 is a Cat B erratum, present in older
revisions of the Neoverse N1 processor core. The workaround is to
set a bit in the CPUACTLR_EL1 system register, which delays instruction
fetch after branch misprediction. This workaround will have a small
impact on performance.

doc: Improve contribution guidelines

- Add some guidance about the type of information a patch author should
provide to facilitate the review (and for future reference).

- Make a number of implicit expectations explicit:
- Every patch must compile.
- All CI tests must pass.

- Mention that the patch author is expected to add reviewers and explain
how to choose them.

- Explain the patch submission rules in terms of Gerrit labels.

Also do some cosmetic changes, like adding empty lines, shuffling some
paragraphs around.

SP804 TIMER is not platform specific, and current code base adds

This patch removes platform specific build flag and adds generic

doc: Refactor the contribution guidelines

Ensuring that each file changed by a patch has the correct copyright and
license information does not only apply to documentation files but to
all files within the source tree.

Move the guidance for copyright and license headers out of the paragraph
about updating the documentation to avoid any confusion.

Also do some cosmetic changes (adding empty lines, fitting in longer
lines in the 80-column limit, ...) to improve the readability of the RST
file.

doc: Stop advising the creation of Phabricator issues

We have noticed that Phabricator (the ticketing system on tf.org [1])
has far less visibility within the community than the mailing list [2].
For this reason, let's drop usage of Phabricator for anything else than
bug reports. For the rest, advise contributors to start a discussion on
the mailing list, where they are more likely to get feedback.
