[PATCH 3/4] PCI/PM: Set pci_dev->set_d3cold in pci_set_power_state

[Huang Ying <ying.huang@intel.com>]

Because now pci_dev->set_d3cold is only used after
pci_set_power_state(, PCI_D3cold) and before pci_set_power_state(,
PCI_D0).  And we will use pci_dev->set_d3cold for D3cold support
during system suspend too, but now pci_dev->set_d3cold is set only in
runtime power management code path now.
