[PATCH v6 10/11] drm/bridge: anx7625: fix anx7625_sink_detect() to return correct hpd status

In the anx7625_sink_detect(), the device is checked to see
if it is a panel bridge, and it always sends a "connected"
status to the connector. When adding the DP port on port 1 of the
anx7625, it incorrectly treats it as a panel bridge and sends an
always "connected" status. Instead of checking the status on the
panel bridge, it's better to check the hpd_status for connectors
that supports hot-plugging. This way, it verifies the hpd_status
variable before sending the status to the connector.
In case of eDP, anx7625_bridge_detect() will not get called because
the bridge->ops condition in anx7625_link_bridge() will not be
satisfied. Since anx7625_sink_detect() is called from
anx7625_bridge_detect(), this results in the sink_detect logic not
being executed for eDP.
