[PATCH 0/2] Drop EDID cache for it6505/anx7625 when the bridge is powered off

[Pin-yen Lin]

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.
