Subject: [PATCH net-next v4 10/11] arm64: dts: ti: k3-j721e-common-proc-board: add mcu cpsw nuss pinmux and phy defs

The TI J721E 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 j721e SoC MCU
Gigabit Ethernet two ports Switch subsystem (CPSW NUSS).
