[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.
