Add a new compatible for J7200 to support the additional modes. In TI's J7200, each of the CPSW5G ethernet interfaces can act as a QSGMII or QSGMII-SUB port. The QSGMII 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. To indicate the interface which will serve as the main QSGMII interface, add a property "ti,qsgmii-main-ports", whose value indicates the port number of the interface which shall serve as the main QSGMII interface. The rest of the interfaces are then assigned QSGMII-SUB mode by default. The property "ti,qsgmii-main-ports" is used to configure the CTRLMMR_ENETx_CTRL register. Depending on the device, it is possible for more than one QSGMII main port to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array of values in order to reuse the property for other devices.
