fsp_baytrail: Fix a possible hanging DisplayPort

On some devices it can happen that DisplayPort TX lanes
    do not work properly if the power gate setup is omitted.
    If that happens, DisplayPort training will fail and therefore
    DisplayPort channel will not work. Both ports are affected.
    It seems that not every CPU shows this effect
    and those that are affected tend to fail more often in a cold
    environment.
    With this fix a board that originally shows this failure
    was running for over 1000 power cycles without issues.
