imx: cortexa53: add network port names for gw74xx

The network two embedded network interface MAC's on the GW74xx can be racy with regards to kernel registration. Add a port path mapping to ensure they do not flip around from boot to boot. On the GW74xx the first RJ45 next to the power-in barrel jack is configured as the WAN (eth0 IMX8MP eqos@0x30bf0000) and the jacks following that (lan1-lan4) are configured as the LAN.
