In commit "drm/i915/display: Increase number of fast wake precharge pulses" we were increasing Fast Wake sync pulse length to fix problems observed on Dell Precision 5490 laptop with AUO panel. Later we have observed this is causing problems on other panels. Fix these problems by increasing Fast Wake sync pulse length as a quirk applied for Dell Precision 5490 with problematic panel.
