I know Saravana has compiled the list of workarounds in preferred order
which excludes this which is good. Anyways I will convey my point. Disabling
mailbox controller node may not be always available option as it could be
providing multiple channels and the stale mboxes reference in SCMI might
be just one of the consumer. Removing mboxes seems only reasonable solution
to me in such scenario.
