Dillon Varone 9fc0cbcb6e drm/amd/display: Require minimum VBlank size for stutter optimization
If the nominal VBlank is too small, optimizing for stutter can cause
the prefetch bandwidth to increase drasticaly, resulting in higher
clock and power requirements. Only optimize if it is >3x the stutter
latency.
