plat/arm: Use common build flag for using generic sp804 driver

SP804 TIMER is not platform specific, and current code base adds
multiple defines to use this driver. Like FVP_USE_SP804_TIMER and
FVP_VE_USE_SP804_TIMER.

This patch removes platform specific build flag and adds generic
flag `USE_SP804_TIMER` to be set to 1 by platform if needed.

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.

TF-A AMU extension: fix detection of group 1 counters.

This patch fixes the bug when AMUv1 group1 counters was
always assumed being implemented without checking for its
presence which was causing exception otherwise.
The AMU extension code was also modified as listed below:
- Added detection of AMUv1 for ARMv8.6
- 'PLAT_AMU_GROUP1_NR_COUNTERS' build option is removed and
number of group1 counters 'AMU_GROUP1_NR_COUNTERS' is now
calculated based on 'AMU_GROUP1_COUNTERS_MASK' value
- Added bit fields definitions and access functions for
AMCFGR_EL0/AMCFGR and AMCGCR_EL0/AMCGCR registers
- Unification of amu.c Aarch64 and Aarch32 source files
- Bug fixes and TF-A coding style compliant changes.

Use abspath to dereference $BUILD_BASE

If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.
