PCI: Introduce pci_get_dsn
Several device drivers read their Device Serial Number from the PCIe
extended config space.
Introduce a new helper function, pci_get_dsn(). This function reads the
eight bytes of the DSN and returns them as a u64. If the capability does not
exist for the device, the function returns 0.
