refactor(fvp): remove RSS usage

Removed RSS usage from the Base AEM FVP platform, as it wasn't
functional on this platform. The Base AEM FVP platform lacks
support for RSS.
Instead, the TC2 platform with RSS is available for actual RSS
interface implementation and testing.

refactor(rss)!: remove PLAT_RSS_NOT_SUPPORTED build option

Removed the PLAT_RSS_NOT_SUPPORTED build option, which was initially
introduced for building the Base AEM FVP platform platform with RSS.
However, we now have a well-defined TC2 platform with RSS, making it
unnecessary to keep this flag.

Note -
Theoretically this is a breaking change. Other platforms could be
using the PLAT_RSS_NOT_SUPPORTED build option. Among upstream platforms,
only the Base AEM FVP uses it right now but we don't know about
downstream platforms.

docs(threat-model): cover threats inherent to receiving data over UART

TF-A supports reading input data from UART interfaces. This opens up
an attack vector for arbitrary data to be injected into TF-A, which is
not covered in the threat model right now.

Fill this gap by:

- Updating the data flow diagrams. Data may flow from the UART into
TF-A (and not only the other way around).

- Documenting the threats inherent to reading untrusted data from a
UART.

chore(auth)!: remove CryptoCell-712/713 support

CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].

As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.

This is a breaking change for downstream platforms which use these
drivers.

[1] https://trustedfirmware-a.readthedocs.io/en/v2.9/about/release-information.html#removal-of-deprecated-drivers
Note that TF-A v3.0 release later got renumbered into v2.10.
