Humm, NULL, NULL. That means find the first node anywhere in the
device tree which matches. This is not going to work too well when you
have multiple i211s.

There is a way so specify a DT node is attached to a specific PCIe
bus/slot. I think you should search only there, so solving the
multiple device issue.
