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.
