Each of the CPSW9G ports in J721e support additional modes like QSGMII. Add a new compatible for J721e to support the additional modes. In TI's J721e, each of the CPSW9G ethernet interfaces can act as a QSGMII main or QSGMII-SUB port. The QSGMII main interface is responsible for performing auto-negotiation between the MAC and the PHY while the rest of the interfaces are designated as QSGMII-SUB interfaces, indicating that they will not be taking part in the auto-negotiation process.
