This regresses vce perf badly on tonga

Maybe I need a better test case or faster cpu or something,
but vce powerplay encode issues disappeared for me with the latest
firmware.
I did eventually find an issue - but I don't know if it's what the
comment below referred to.
vaapi cbr since the mesa commit that enabled dual instance
can sometimes produce different md5sums, though the vid is visually
OK. Maybe gstreamer timing based as it can be reduced by changing
cpufreq from on_demand to perf or adding ! queue !. Higher bitrates
seem to not have the issue, cqp doesn't seem affected.
