arm64: dts: ti: k3-am642-evm: Add ICSSG0 overlay for dual EMAC support
Add device tree overlay to enable ICSSG0 dual EMAC support on AM642 EVM. This overlay enables both ICSSG0 Ethernet interfaces (port0 and port1) in dual EMAC mode. Users can combine this with the existing ICSSG1 overlay to enable all four ICSSG interfaces if needed.
