The anx7625_link_bridge() checks if a device is not a panel
bridge and add DRM_BRIDGE_OP_HPD and DRM_BRIDGE_OP_DETECT
flags to the drm_bridge->ops. However, on port 1 of the anx7625
bridge, any device added is always treated as a panel bridge,
preventing connector_detect() from being called. To resolve
this, instead of just checking if it is a panel bridge, verify
the type of device based on aux whether it is a DisplayPort or
eDP panel. If the device is not of the eDP type, add
DRM_BRIDGE_OP_HPD and DRM_BRIDGE_OP_DETECT flags to the to
the drm_bridge->ops.
