[PATCH v4 1/4] PCI/portdrv: Make use of pci_dev::bridge_d3 for checking the D3 possibility

[Manivannan Sadhasivam]

PCI core is already caching the value of pci_bridge_d3_possible() in
pci_dev::bridge_d3 during pci_pm_init(). Since the value is not going to
change, let's make use of the cached value.
