PCI: export SMBIOS provided firmware instance and label to sysfs
This patch exports SMBIOS provided firmware instance and label of
onboard PCI devices to sysfs. New files are:
/sys/bus/pci/devices/.../label which contains the firmware name for
the device in question, and
/sys/bus/pci/devices/.../index which contains the firmware device type
instance for the given device.
