Use the overlay to configure CPSW9G ports in QSGMII mode with the Add-On Ethernet Card connected to the ENET Expansion 1 slot on the EVM. Add support to reset the PHY from kernel by using gpio-hog and gpio-reset. Add aliases for CPSW9G ports to enable kernel to fetch MAC Addresses directly from U-Boot.
