Query the port partner's SVIDs when the DisplayPort driver sysfs
is not recognized so that the USB HAL can identify whether or not
the port partner supports Thunderbolt.
Test: manual verification on device - test to see that cableStatus
is set to NOT_CAPABLE on hub that supports Thunderbolt but not
DisplayPort Alt Mode. Then verify that device not capable of being
a DisplayPort sink but does support Thunderbolt does not trigger
this status.
