[PATCH v3 06/12] PCI: Explicitly mark USB4 NHI devices as removable

[Mario Limonciello]

USB4 class devices are also removable like Intel Thunderbolt devices.

Drivers of downstream devices use this information to declare functional
differences in how the drivers perform by knowing that they are connected
to an upstream TBT/USB4 port.
