arm64: dts: ti: k3-j721s2: Add overlay to enable main CPSW2G with GESI
The MAIN CPSW2G instance of CPSW on J721S2 SoC can be enabled with the GESI
Expansion Board connected to the J7 Common-Proc-Board. Use the overlay
to enable this.
Add alias for the MAIN CPSW2G port to enable kernel to fetch MAC address
directly from U-Boot.
