Merge branch 'pci/misc' into next

* pci/misc:
  PCI: Remove pcie_cap_has_devctl()
  PCI: Support PCIe Capability Slot registers only for ports with slots
  PCI: Remove PCIe Capability version checks
  PCI: Allow PCIe Capability link-related register access for switches
  PCI: Add offsets of PCIe capability registers
  PCI: Tidy bitmasks and spacing of PCIe capability definitions
  PCI: Remove obsolete comment reference to pci_pcie_cap2()
  PCI: Clarify PCI_EXP_TYPE_PCI_BRIDGE comment
  PCI: Rename PCIe capability definitions to follow convention
  PCI: Disable decoding for BAR sizing only when it was actually enabled
  PCI: Add comment about needing pci_msi_off() even when CONFIG_PCI_MSI=n
  PCI: Add pcibios_pm_ops for optional arch-specific hibernate functionality
