[ Upstream commit 385c3e4c29e1d4ce8f68687a8c84621e4c0e0416 ]
[Why] In 2560x1600@240p eDP panel, driver use lowest voltage level to play 1080p video cause underflow. According to HW SPEC, the senario should use high voltage level.
[How] ChromaPre value is zero when bandwidth validation. Correct ChromaPre calculation.
