that don't have display blocks and the driver should work on those.

pci_is_thunderbolt_attached() looks at the hierarchy of the PCIe device
to determine if any bridge along the way has the is_thunderbolt bit set.
This bit will only be set when one of the devices in the hierarchy is an
Intel Thunderbolt device.
