    arm64: apply ARM64_ERRATUM_843419 workaround for Brahma-B53 core
    
    The Broadcom Brahma-B53 core is susceptible to the issue described by
    ARM64_ERRATUM_843419 so this commit enables the workaround to be applied
    when executing on that core.
    
    Since there are now multiple entries to match, we must convert the
    existing ARM64_ERRATUM_843419 into an erratum list and use
    cpucap_multi_entry_cap_matches to match our entries.
