Jouni Högander fe07214474 drm/i915: Use 18 fast wake AUX sync len
[ Upstream commit 2d6f2f79e0 ]

HW default for wake sync pulses is 18. 10 precharge and 8 preamble. There
is no reason to change this especially as it is causing problems with
certain eDP panels.

v3: Change "Fixes:" commit
v2: Remove "fast wake" repeat from subject
