drm/i915/display: Increase number of fast wake precharge pulses

Browse source

Increasing number of fast wake sync pulses seem to fix problems with
certain PSR panels. This should be ok for other panels as well as the eDP
specification allows 10...16 precharge pulses and we are still within that
range.

v3: mention laptop model and panel manufacturer and model in comment
v2: add comment explaining pulse count is increased
