This seems to be not the only instance, there are other places where plx
prefix is used. There are 8 instances in total, 4 ARM (in fact all
Toradex device trees) and 4 PowerPC.

One device is already documented in
Documentation/devicetree/bindings/trivial-devices.txt:
plx,pex8648               48-Lane, 12-Port PCI Express Gen 2 (5.0 GT/s)
Switch

I suggest to just add plx as a valid vendor prefix by adding plx to
Documentation/devicetree/bindings/vendor-prefixes.txt:
plx	Broadcom Corporation (formerly PLX Technology)
