This patch implements SMCCC_ARCH_WORKAROUND_4 and
allows discovery through SMCCC_ARCH_FEATURES.
This mechanism is enabled if CVE_2024_7881 [1] is enabled
by the platform. If CVE_2024_7881 mitigation
is implemented, the discovery call returns 0,
if not -1 (SMC_ARCH_CALL_NOT_SUPPORTED).
For more information about SMCCC_ARCH_WORKAROUND_4 [2], please
refer to the SMCCC Specification reference provided below.

We have one entry per CPU features but most of the time we just add
CPU feature and its not touched again, so considering to generalize
anything with FEAT_XXXX additions to use `cpufeat` as subsection scope.
Also, some time we don't add a scope for CPU feature this causes problem
while generating release notes as CPU feature additions ends up in wrong
section.

Distros (e.g. Buildroot and Android) can have different secure partition
layout.
This commit iterates the DPE metadata table and finds index (i) for the
first entry of the secure partition, connecting with the defined secure
partition number NUM_SP, so the last secure partition index is:
i + NUM_SP - 1
Instead of setting the certificate in hard code, dynamically enables the
certificate for the last secure partition base on calculated index.

The previous code used 64-bit registers as the target and source for
load and store operations on 32-bit hardware registers. In certain
cases (e.g., when using USART1 as the debug console), this could result
in deadlocks where the A35 gets stuck in a permanent loop due to test
conditions that are never fulfilled.
To resolve this issue, 32-bit registers are now used for these
operations.
