Sandrine Bailleux e686cdb450 feat(mbedtls): update to 3.4.1
Update TF-A documentation to recommend using the latest and greatest
release of mbedTLS library to this date, i.e. version 3.4.1. The
upgrade was successfully tested by the OpenCI running all existing
test configs, in particular trusted boot and measured boot related
ones.

The reason for this upgrade is simply to obey TF-A's guideline to
always use up-to-date security libraries. mbedTLS 3.4.1 release
notes [1] do not list any changes that should affect TF-A.

Trusted Firmware-A
==================

Trusted Firmware-A (TF-A) is a reference implementation of secure world software
for `Arm A-Profile architectures`_ (Armv8-A and Armv7-A), including an Exception
Level 3 (EL3) `Secure Monitor`_. It provides a suitable starting point for
productization of secure world boot and runtime firmware, in either the AArch32
or AArch64 execution states.

TF-A implements Arm interface standards, including:

-  `Power State Coordination Interface (PSCI)`_
-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
-  `SMC Calling Convention`_
-  `System Control and Management Interface (SCMI)`_
-  `Software Delegated Exception Interface (SDEI)`_

The code is designed to be portable and reusable across hardware platforms and
software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A
with reference implementations of Arm standards to benefit developers working
with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration
testing, on any secure world code derived from TF-A.
