'linux,pci-domain' property provides the PCI domain number for the PCI
endpoint controllers in a SoC. If this property is not present, then an
unstable (across boots) unique number will be assigned.

Use this property to specify the domain number based on the actual hardware
instance of the PCI endpoint controllers in SDX55 SoC.
