This patch adds the following changes to complete the existing
TRNG implementation:
1. Adds a feature specific scope for buildlog generation.
2. Updates the docs on the build flag "TRNG_SUPPORT" and its values.
3. Makefile update and improves the existing comments at few sections
for better understanding of the underlying logic.
- Remove mentions of Arm SGM-775 and MediaTek MT6795 platforms.
Both platform ports were deleted from TF-A source tree in the
last release (v2.7).
- Remove mention of Arm Morello platform, as it now has a dedicated
documentation page accessible from the table of contents
(see docs/plat/arm/morello/).

feat: pass SMCCCv1.3 SVE hint bit to dispatchers
SMCCCv1.3 introduces the SVE hint bit added to the SMC FID (bit 16)
denoting that the world issuing an SMC doesn't expect the callee to
preserve the SVE state (FFR, predicates, Zn vector bits greater than
127). Update the generic SMC handler to copy the SVE hint bit state
to SMC flags and mask out the bit by default for the services called
by the standard dispatcher. It is permitted by the SMCCC standard to
ignore the bit as long as the SVE state is preserved. In any case a
callee must preserve the NEON state (FPCR/FPSR, Vn 128b vectors)
whichever the SVE hint bit state.
This change updates the version of the Node Version Manager suggested by
the prerequisites documentation. The NVM installation command line hint
has been replaced with the snippet provided by NVM's user guide, and the
second line now automatically installs a version of Node.js compatible
with TF-A's repository scripts.

Platforms which implement pwr_domain_pwr_down_wfi differ substantially
in behaviour. However, different cpus require similar sequences to power
down. This patch tightens the behaviour of these platforms to end on a
wfi loop after performing platform power down. This is required so that
platforms behave more consistently on power down, in cases where the wfi
can fall through.
Add documentation how to build EL3 SPMC,
briefly describes all FF-A interfaces,
SP boot flow, SP Manifest, Power Management,
Boot Info Protocol, Runtime model and state
transition and Interrupt Handling.
