Merge tag 'pci-v4.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:

 - add ASPM L1 substate support

 - enable PCIe Extended Tags when supported

 - configure PCIe MPS settings on iProc, Versatile, X-Gene, and Xilinx

 - increase VPD access timeout

 - add ACS quirks for Intel Union Point, Qualcomm QDF2400 and QDF2432

 - use new pci_irq_alloc_vectors() in more drivers

 - fix MSI affinity memory leak

 - remove unused MSI interfaces and update documentation

 - remove unused AER .link_reset() callback

 - avoid pci_lock / p->pi_lock deadlock seen with perf

 - serialize sysfs enable/disable num_vfs operations

 - move DesignWare IP from drivers/pci/host/ to drivers/pci/dwc/ and
   refactor so we can support both hosts and endpoints

 - add DT ECAM-like support for HiSilicon Hip06/Hip07 controllers

 - add Rockchip system power management support

 - add Thunder-X cn81xx and cn83xx support

 - add Exynos 5440 PCIe PHY support
