Lots of Zhaoxin PCIe components have no ACS Capability Structure,
but do have ACS-like capability which ensures DMA isolation.
This patch makes isolated devices could be directly assigned to
different VMs through IOMMU.

Raymond Pang (3):
  PCI: Add Zhaoxin Vendor ID
  PCI: Add ACS quirk for Zhaoxin's multi-function devices
  PCI: Add ACS quirk for Root/Downstream Ports
