From: Eric Yang <Eric.Yang2@xxxxxxx> [Why] Virtual sink is used when set mode happens on a disconnected display to allow the mode set to proceed. This did not work with MST because the logic for acquiring stream encoder uses stream signal to determine the special handling is required, and stream signal is virtual instead of DP in this case. [How] Use link type to decide instead.
