arm64: fix ARM64_WORKAROUND_SPECULATIVE_UNPRIV_LOAD
JIRA: https://issues.redhat.com/browse/RHEL-31321
CVE: CVE-2024-26670
Rework ARM64_WORKAROUND_SPECULATIVE_UNPRIV_LOAD workaround to handle a new variant of the problem. We don't have any a520 cores which would exhibit the problem, so sanity test is best we can do.
