arm64: dts: imx8mp-venice-gw73xx: add mac addr for eth1
The SoM used on this board does not bring down the pins for the QOS
ethernet and instead offers the 2nd ethernet as a PCI GbE device.
Set the alias as such and add the PCI bus topology for eth1 so that
boot firmware can set the local-mac-address property.
The eth1 device is behind a PCI switch:
