Subject: [GIT PULL] PCI changes for v4.11

PCI changes:

  - 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
