Subject: [PATCH] drivers/firmware/edd: Treat "XPRS" host bus type the
 same as "PCI"

PCI Express devices will return "XPRS" host bus type during BIOS EDD
call.  "XPRS" should be treated just like "PCI" so that the proper
pci_dev symlink will be created.  Scripts such as fcoe-edd.sh will
then work correctly.
