fix: backtrace stack unwind misses lr adjustment

When pointer authentication is used the frame record return address
includes the pointer authentication code hence it must be masked out
when willing to compare the pointer value with another address or
checking its validity. The stack unwind function missed one case of
adjusting the return address leading to a misinterpreted corrupted stack
frame error message.

fix(qemu): enable SVE and SME

Starting with QEMU v3.1.0 (Dec 2018), QEMU's TCG emulation engine supports
the SVE architecture extension. In QEMU v7.1.0 (Aug 2022) it also gained
SME support.

As it stands today, running TF-A under QEMU with "-cpu max" makes Linux
hang, because SME and SVE accesses trap to EL3, but are never handled
there. This is because the Linux kernel sees the SVE or SME feature bits,
and assumes firmware has enabled the feature for lower exception levels.
This requirement is described in the Linux kernel booting protocol.

Enable those features in the TF-A build, so that BL31 does the proper
EL3 setup to make the feature usable in non-secure world.
We check the actual feature bits before accessing SVE or SME registers,
so this is safe even for older QEMU version or when not running with
-cpu max. As SVE and SME are AArch64 features only, do not enable them
when building for AArch32.

feat(ethos-n)!: add support for SMMU streams

The Arm(R) Ethos(TM)-N NPU driver now supports configuring the SMMU
streams that the NPU shall use and will therefore no longer delegate
access to these registers to the non-secure world. In order for the
driver to support this, the device tree parsing has been updated to
support parsing the allocators used by the NPU and what SMMU stream that
is associated with each allocator.

To keep track of what NPU device each allocator is associated with, the
resulting config from the device tree parsing will now group the NPU
cores and allocators into their respective NPU device.

The SMC API has been changed to allow the caller to specify what
allocator the NPU shall be configured to use and the API version has
been bumped to indicate this change.

feat(debug): add helpers for aborts on AARCH32

New helper functions are created to handle data & prefetch aborts
in AARCH32. They call platform functions, just like what
report_exception is doing.
As extended MSR/MRS instructions (to access lr_abt in monitor mode)
are only available if CPU (Armv7) has virtualization extension,
the functions branch to original report_exception handlers if this is
not the case.
Those new helpers are created mainly to distinguish data and prefetch
aborts, as they both share the same mode.
This adds 40 bytes of code.

feat(fvp): support building RSS comms driver

On one hand, there is currently no upstream platform supporting the
RSS. On the other hand, we are gradually introducing driver code for
RSS. Even though we cannot test this code in the TF-A CI right now, we
can at least build it to make sure no build regressions are introduced
as we continue development.

This patch adds support for overriding PLAT_RSS_NOT_SUPPORTED build
flag (which defaults to 1 on the Base AEM FVP) from the command
line. This allows introducing an ad-hoc CI build config with
PLAT_RSS_NOT_SUPPORTED=0, which will correctly pull in the RSS and MHU
source files. Of course, the resulting firmware will not be
functional.
