Merge branch 'pci/encapsulate'

  - Move many symbols from public linux/pci.h to subsystem-private
    drivers/pci/pci.h (Kelsey Skunberg)

  - Unexport pci_bus_get() and pci_bus_sem since they're not needed by
    modules (Kelsey Skunberg)

  - Remove unused pci_block_cfg_access() et al (Kelsey Skunberg)

* pci/encapsulate:
  PCI: Make pci_set_of_node(), etc private
  PCI: Make pci_enable_ptm() private
  PCI: Make pcie_set_ecrc_checking(), pcie_ecrc_get_policy() private
  PCI: Make pci_ats_init() private
  PCI: Make pcie_update_link_speed() private
  PCI: Make pci_bus_get(), pci_bus_put() private
  PCI: Make pci_hotplug_io_size, mem_size, and bus_size private
  PCI: Make pci_save_vc_state(), pci_restore_vc_state(), etc private
  PCI: Make pci_get_host_bridge_device(), pci_put_host_bridge_device() private
  PCI: Make pci_check_pme_status(), pci_pme_wakeup_bus() private
  PCI: Make PCI_PM_* delay times private
  PCI: Unexport pci_bus_sem
  PCI: Unexport pci_bus_get() and pci_bus_put()
  PCI: Remove pci_block_cfg_access() et al (unused)
