I suppose this helps with validation of device trees.  However, nodes
for PCI devices are not supposed to have a "compatible" property as
the PCI vendor and device IDs are supposed to be used to identify a
device.

That does raise the question how a schema for additional properties
for PCI device nodes is supposed to be defined...
