[Freedreno] [PATCH v6 2/3] drm/bridge_connector: stop filtering events in drm_bridge_connector_hpd_cb()

[Dmitry Baryshkov]

In some cases the bridge drivers would like to receive hotplug events
even in the case new status is equal to the old status. In the DP case
this is used to deliver "attention" messages to the DP host. Stop
filtering the events in the drm_bridge_connector_hpd_cb() and let
drivers decide whether they would like to receive the event or not.
