Merge branch 'pci/portdrv'

  - move pcieport_if.h to drivers/pci/pcie/ to encapsulate it (Frederick
    Lawler)

  - merge pcieport_if.h into portdrv.h (Bjorn Helgaas)

  - move workaround for BIOS PME issue from portdrv to PCI core (Bjorn
    Helgaas)

  - completely disable portdrv with "pcie_ports=compat" (Bjorn Helgaas)

  - remove portdrv link order dependency (Bjorn Helgaas)

  - remove support for unused VC portdrv service (Bjorn Helgaas)

  - simplify portdrv feature permission checking (Bjorn Helgaas)

  - remove "pcie_hp=nomsi" parameter (use "pci=nomsi" instead) (Bjorn
    Helgaas)

  - remove unnecessary "pcie_ports=auto" parameter (Bjorn Helgaas)

  - use cached AER capability offset (Frederick Lawler)

  - don't enable DPC if BIOS hasn't granted AER control (Mika Westerberg)

  - rename pcie-dpc.c to dpc.c (Bjorn Helgaas)
