refactor(cpus): optimize CVE checking

This patch replaces the use of EXTRA functions
with using erratum entries check
to verify CVE mitigation application for some of
the SMCCC_ARCH_WORKAROUND_* calls.

Previously, EXTRA functions were individually implemented for
each SMCCC_ARCH_WORKAROUND_*, an approach that becomes unmanageable
with the increasing number of workarounds.
By looking up erratum entries for CVE check, the process is streamlined,
reducing overhead associated with creating and
maintaining EXTRA functions for each new workaround.

New Errata entries are created for SMC workarounds and
that is used to target cpus that are uniquely impacted
by SMC workarounds.
