docs: fix mailing lists URLs

With the transition to mailman3, the URLs of TF-A and TF-A Tests
mailing lists have changed. However, we still refer to the old
location, which are now dead links.

Update all relevant links throughout the documentation.

There is one link referring to a specific thread on the TF-A mailing
list in the SPM documentation, for which I had to make a guess as to
what's the equivalent mailman3 URL. The old URL scheme indicates that
the thread dates from February 2020 but beyond that, I could not make
sense of the thread id within the old URL so I picked the most likely
match amongst the 3 emails posted on the subject in this time period.

- Used by an SP to signal it has finished initializing.
- To resume the normal world after handling a secure interrupt
that interrupted the normal world.
- To relinquish control back to the normal world.

feat(spmc): add function to determine the return path from the SPMC

Use knowledge of the target partition ID and source security state
to determine which route should be used to exit the SPMC.

There are 3 exit paths:
1) Return to the normal world via the SPMD, this will take care of
switching contexts if required.
2) Return to the secure world when the call originated in the normal
world and therefore switch contexts.
3) Return to the secure world when the call originated in the secure
world, therefore we can return directly.

feat(spmd): enable handling of FF-A SMCs with the SPMC at EL3

Any FF-A SMC that arrives from the normal world is handled by the
SPMD before being forwarded to the SPMC. Similarly any SMC
arriving from the secure world will hit the SPMC first and be
forwarded to the SPMD if required, otherwise the SPMC will
respond directly.

This allows for the existing flow of handling FF-A ABI's when
the SPMC resides at a lower EL to be preserved.

In order to facilitate this flow the spmd_smc_forward function
has been split and control is either passed to the SPMC or it is
forwarded as before. To allow this the flags and cookie parameters
must now also be passed into this method as the SPMC must be able to
provide these when calling back into the SPMD handler as appropriate.

feat(spmd): update SPMC init flow to use EL3 implementation

Allow the SPMD to initialise an SPMC implementation at EL3 directly
rather than at a lower EL.
This includes removing the requirement to parse an SPMC manifest to
obtain information about the SPMC implementation, in this case since the
SPMD and SPMC reside in the same EL we can hardcode the required
information directly.

feat(spmc): add FF-A secure partition manager core

This patch introduces the core support for enabling an SPMC in EL3
as per the FF-A spec.

The current implemented functionality is targeted to enable
initialization of the SPMC itself and initial support for
bringing up a single S-EL1 SP.

This includes initialization of the SPMC's internal state,
parsing of an SP's manifest, preparing the cpu contexts and
appropriate system registers for the Secure Partition.

The spmc_smc_handler is the main handler for all incoming SMCs
to the SPMC, FF-A ABI handlers and functionality will
be implemented in subsequent patches.

The current implementation uses plat_arm API under generic code.

Henceforth, removing the weak API with a configurable macro "TWED_DELAY"
of numeric data type in generic code and simplifying the implementation.
By default "TWED_DELAY" is defined to zero, and the delay value need to
be explicitly set by the platforms during buildtime.
