drm/i915: Fix fast wake AUX sync len
commit e1c71f8f918047ce822dc19b42ab1261ed259fd1 upstream.
Fast wake should use 8 SYNC pulses for the preamble
and 10-16 SYNC pulses for the precharge. Reduce our
fast wake SYNC count to match the maximum value.
We also use the maximum precharge length for normal
AUX transactions.
