Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Revert sysfs "rescan" renames that broke apps (Kelsey Skunberg)

     PCI_BUS_RELATIONS2 (Long Li)

   - Refactor to prepare for virtual PCI on non-x86 architectures (Boqun
     Feng)

   - Use pci_parse_request_of_pci_ranges() (Rob Herring)

   - Add support for endpoint mode and related DT updates (Vidya Sagar)

   - Reduce -EPROBE_DEFER error message log level (Thierry Reding)

  Qualcomm PCIe controller driver:

   - Restrict class fixup to specific Qualcomm devices (Bjorn Andersson)

  Synopsys DesignWare PCIe controller driver:

   - Refactor core initialization code for endpoint mode (Vidya Sagar)

     Abraham I)

  TI DRA7xx PCIe controller driver:

   - Fix MSI IRQ handling (Vignesh Raghavendra)

  TI Keystone PCIe controller driver:

   - Allow AM654 endpoint to raise MSI-X interrupt (Kishon Vijay Abraham I)

  Miscellaneous:

   - Quirk ASMedia XHCI USB to avoid "PME# from D0" defect (Kai-Heng
     Feng)
