The GW73xx baseboard needs a PCI dt adjustment for revC/D based on a change of the PCIe switch. Make sure we are only doing this for a pci based ethernet to avoid causing a boot hang when the ethernet1 alias points to eqos or fec. To know this is a pcie device ensure the alias begins with the pcie controller.
