This mainly fixes the use case when the user changes the external monitor when the system is suspended. Without this series, both of the bridges will skip the EDID read and returned the cached one after resume. Apart from that, we also observed a DP-to-HDMI bridge expects an EDID read after it's powered on. This patch also works around the problem by always triggering the EDID read after the system resume.
