board: gateworks: venice: add fixup for GW73xx-C+

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.
