Add device-tree node path to the verbose output
Adds the path of the device-tree node of a PCI device to the lspci -v
output, like so:
0021:00:00.0 PCI bridge: IBM Device 03dc (prog-if 00 [Normal decode])
DT Node: /sys/firmware/devicetree/base/pciex@3fffe41100000/pci@0
This is added as a generic property to struct pci_device and populated
by the sysfs backend. Other platforms may find it useful though.
