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

[Michael Chan]

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.
