Madhukar Pappireddy 42422622f9 feat(simd): add sve state to simd ctxt struct
This patch extends the simd data structure to hold the SVE state. A new
build flag CTX_INCLUDE_SVE_REGS is introduced in this patch to enable
SVE context management.

Necessary precautions are taken such as ensuring the field offsets are
not changed and necessary padding is added for alignment reasons.

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.
