DispSync: don't compensate for wakeup latency

Browse Source 
This change removes the wakeup latency compensation from the software-generated
vsync events.  Choreographer can't handle timestamps in the future, so don't
aim for early wake-ups with the expectation that the actual wake-up will be
late.
