Don't dereference a device node that isn't there. A "shouldn't
happen" case, but someone ran into it with a possibly misconfigured
device tree.

25-pci-address-cache.patch
The core EEH file is rather large. This patch splits out a self-contained
chunk of it into its own file. This is the chunk that performes the
caching and lookup of pci devices based on the i/o addresses of thier
resoures. This code is almos architecture-independent and could be
used by any system that wanted to find a pci device based only on
the i/o address used by the device.
