Merge branch 'pci/enumeration'
- 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
