The binding docs live in the kernel:
https://www.kernel.org/doc/Documentation/devicetree/bindings/pci/host-generic-pci.txt
(which reference the upstream openfirmware specs):
http://www.firmware.org/1275/practice/imap/imap0_9d.pdf

so we can provide a brief summary comment here, but if the kernel
binding docs are confusing (which they kind of are) we should really
get them improved...

On the 'compatible' string:
https://www.kernel.org/doc/Documentation/devicetree/bindings/pci/host-generic-pci.txt
doesn't say anything about using "pci" here in either the
text or the example binding.
