The GW73xx-C revision and onward replaced the 5-port PCIe switch with a 4-port (dropping PCIe to one of the miniPCIe sockets) due to part availability. This moved the PCI bus of the GbE eth1 device. Use a fixup to adjust the dt accordingly so that local-mac-address assigned from dt works on new revision boards.
While we are at it, rename 'blob' to 'fdt' for clarity.
