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)

* pci/portdrv:
  PCI/DPC: Rename from pcie-dpc.c to dpc.c
  PCI/DPC: Do not enable DPC if AER control is not allowed by the BIOS
  PCI/AER: Use cached AER Capability offset
  PCI/portdrv: Rename and reverse sense of pcie_ports_auto
  PCI/portdrv: Encapsulate pcie_ports_auto inside the port driver
  PCI/portdrv: Remove unnecessary "pcie_ports=auto" parameter
  PCI/portdrv: Remove "pcie_hp=nomsi" kernel parameter
  PCI/portdrv: Remove unnecessary include of <linux/pci-aspm.h>
  PCI/portdrv: Simplify PCIe feature permission checking
  PCI/portdrv: Remove unused PCIE_PORT_SERVICE_VC
  PCI/portdrv: Remove pcie_port_bus_type link order dependency
  PCI/portdrv: Disable port driver in compat mode
  PCI/PM: Clear PCIe PME Status bit for Root Complex Event Collectors
  PCI/PM: Clear PCIe PME Status bit in core, not PCIe port driver
  PCI/PM: Move pcie_clear_root_pme_status() to core
  PCI/portdrv: Merge pcieport_if.h into portdrv.h
  PCI/portdrv: Move pcieport_if.h to drivers/pci/pcie/
