Add USXGMII mode to the extra_modes member of the J784S4 SoC data. Additionally, convert the IF statement in am65_cpsw_nuss_mac_config() to SWITCH statement to scale for new modes. Configure MAC control register for supporting USXGMII mode and add MAC_5000FD in the "mac_capabilities" member of struct "phylink_config".
