- Implement portdrv .shutdown() method that calls service driver .remove()
  methods (which disables interrupt generation as required by .shutdown()),
  but doesn't disable bus mastering (which hangs on Loongson LS7A because
  of a hardware defect) (Huacai Chen)

- Prevent MRRS increases for devices below Loongson LS7A to avoid hardware
  limitations (Huacai Chen)

- Ignore devices with a firmware (DT/ACPI) node that says the device is
  disabled (Rob Herring)

* pci/enumeration:
  PCI: Honor firmware's device disabled status
  PCI: loongson: Add more devices that need MRRS quirk
  PCI: loongson: Prevent LS7A MRRS increases
  PCI/portdrv: Prevent LS7A Bus Master clearing on shutdown
