- add managed interface to get PCI host bridge resources from OF (Jan
    Kiszka)

  - add support for unbinding generic PCI host controller (Jan Kiszka)

  - fix memory leaks when unbinding generic PCI host controller (Jan Kiszka)

* pci/resource:
  PCI: Enable PCI_DOMAINS along with generic PCI host controller
  PCI: Add support for unbinding the generic PCI host controller
  PCI: Rework of_pci_get_host_bridge_resources() to devm_of_pci_get_host_bridge_resources()
  PCI: Use dev_printk() in of_pci_get_host_bridge_resources()
  PCI: Pass struct device to of_pci_get_host_bridge_resources()
  PCI: Rename of_pci_get_host_bridge_resources() device node parameter
  PCI: Fix devm_pci_alloc_host_bridge() memory leak
  PCI: Make pci_get_new_domain_nr() static
