PCIe only permits 1 device on an endpoint, so some devices ignore the device
part of B:D:F probing. Although ARI likely fixes this, not all platforms
support ARI completely or correctly, so some devices end up showing up 32 times
on the bus.
This was found during bringup of POWER9/Talos. The OPAL firmware source
includes a comment stating that ARI needs to be implemented. At that point this
may become redundant. But until then, this is needed for POWER9 bringup.
