[Yijing Wang]

v1->v2: Modify pci_get_dsn to pci_device_serial_number,
	    power off slot before remove the old device during resume to avoid
		old .remove() method to touch new hardware.
		Fix other typo and fail check problems.
		Split the list_empty() guard into new patch.

  PCI: introduce PCIe Device Serial Number Capability support
  PCI,pciehp: avoid add a device already exist before suspend during
