Not sure if this needs to be fixes though. With addition of notifications
in the FF-A driver(since v6.7), host can send FF-A messages beyond 0x7F.
But since the pKVM FF-A proxy support is not yet updated to v1.1, so I
don't think it needs to be tagged as fix. Just thought I will mention it
here anyways.
