According to the PCI firmware spec, there is only one assigned UUID used
for PCI system so rename the device_label_dsm_uuid to something more
common as: pci_acpi_dsm_uuid and put it in drivers/pci/pci-acpi.c. Make
that uuid array extern in the pci.h so that other code can also make use
of it.
This patch shouldn't bring any functional change.
