arm64: dts: ti: k3-j7200-common-proc-board: add mcu cpsw nuss pinmux and phy defs
The TI J7200 EVM base board has TI DP83867 PHY connected to external CPSW NUSS Port 1 in rgmii-rxid mode. Hence, add pinmux and Ethernet PHY configuration for TI J7200 SoC MCU Gigabit Ethernet two ports Switch subsystem (CPSW NUSS).
