Update efuse data for MT8188 displayport. The DP monitor can not display when DUT connected to USB-c to DP dongle. Analysis view is invalid DP efuse data. Fixes: 350c3fe907fb ("drm/mediatek: dp: Add support MT8188 dp/edp function") Changes in V2: - Add Fixes tag. - Update the commit title. - Update the commit description.
