Hi Will,

This patch series enable the Brahma-B53 CPU to be matched for the
ARM64_ERRATUM_845719 and ARM64_ERRATUM_843419 and while we are it, also
whitelists it for SSB and spectre v2.

The silicon-errata.rst document is updated accordingly, we unfortunately
do not have internal numbers tracking those errata.
