If PSR is enabled our HW might be still in sleep when performing wait
vblanks on DSB. Now as we are switching to using VRR send push as
"Frame Change" event for PSR we are observing these timeouts as only
"Frame Change" event is VRR send push.
Fix this by triggering doing VRR send push before waiting vblank.
