Manoj Kumar AVM fb472b0553 hqd: Do not process WFD teardown as part of HDMI connection
WFD teardown was required when HDMI is connected on V4L2
architecture. This is because WFD connection is using HDMI
piggyback connection. Since SurfaceFlinger can honour only
one active external display, we have to teardown WFD
connection to process HDMI connection.

This is no longer applicable on VDS architecture. WFD connection
is established using Virtual Display adapter.
WFD Stack listen to HDMI broadcast event and initiate wfd teardown.
