board: gateworks: venice: fix dt adjustment for gw73xx baseboard for imx8mp

Browse source 
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.
