5.11: DP does not recover from display blank

This is the recurrence of #234 (closed) on 5.11. The workaround there

echo performance > /sys/devices/platform/soc@0/3d400000.memory-controller/devfreq/3d400000.memory-controller/governor
echo performance > /sys/devices/platform/soc@0/32700000.interconnect/devfreq/32700000.interconnect/governor

still works reliably
