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.
