Merge branches 'pci/aspm', 'pci/enumeration', 'pci/hotplug', 'pci/misc', 'pci/msi', 'pci/resource' and 'pci/virtualization' into next

Browse source 
* pci/aspm:
  PCI/ASPM: Simplify Clock Power Management setting
  PCI: Use dev->has_secondary_link to find downstream PCIe links
  PCI/ASPM: Use dev->has_secondary_link to find downstream links
  PCI: Add dev->has_secondary_link to track downstream PCIe links
  PCI/ASPM: Remove redundant PCIe port type checking
  PCI/ASPM: Drop __pci_disable_link_state() useless "force" parameter

* pci/enumeration:
  PCI: Remove unused pci_scan_bus_parented()
  xen/pcifront: Don't use deprecated function pci_scan_bus_parented()
  PCI: designware: Use pci_scan_root_bus() for simplicity
  PCI: tegra: Remove tegra_pcie_scan_bus()
  PCI: mvebu: Remove mvebu_pcie_scan_bus()

* pci/hotplug:
  PCI: pciehp: Wait for hotplug command completion where necessary
  PCI: Propagate the "ignore hotplug" setting to parent
  ACPI / hotplug / PCI: Check ignore_hotplug for all downstream devices
  PCI: pciehp: Drop pointless label from pciehp_probe()
  PCI: pciehp: Drop pointless ACPI-based "slot detection" check

* pci/misc:
  PCI: Remove unused pci_dma_burst_advice()
  PCI: Remove unused pcibios_select_root() (again)
  PCI: Remove unnecessary #includes of <asm/pci.h>
  PCI: Include <linux/pci.h>, not <asm/pci.h>

* pci/msi:
  PCI/MSI: Remove unused pci_msi_off()
  PCI/MSI: Drop pci_msi_off() calls from quirks
  ntb: Drop pci_msi_off() call during probe
  virtio_pci: drop pci_msi_off() call during probe
  PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI
  PCI/MSI: Export pci_msi_set_enable(), pci_msix_clear_and_set_ctrl()
  PCI/MSI: Rename msi_set_enable(), msix_clear_and_set_ctrl()

* pci/resource:
  PCI: Add pci_bus_addr_t

* pci/virtualization:
  ACPI / PCI: Account for ARI in _PRT lookups
  PCI: Move pci_ari_enabled() to global header
  PCI: Add function 1 DMA alias quirk for Marvell 9120
  PCI: Add ACS quirks for Intel 9-series PCH root ports
