Bug description:
  [impact]
  The default sync pulse length for fast wake AUX transactions was changed from 
18 to 10, which was causing issues with some eDP panels.

  [fix]
  Revert the sync pulse length for fast wake AUX transactions back to the 
hardware default of 18 (10 precharge + 8 preamble).

  [test cases]
  1. configure with thunderbolt.clx=0.
  2. check edp's behavior and it should work well and there's no garbage.

  [where the issue could happen]
  low, By reverting this setting back to the default, this commit restores 
stability for configurations using fast wake AUX transactions, especially those 
involving eDP panels that were incompatible with the shorter sync pulse length. 
The longer, hardware-default sync pulse length is compatible with more use 
cases.
