[PATCH net-next v4 08/11] arm64: dts: k3-am654-base-board: add mcu cpsw nuss pinmux and phy defs

AM654 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 am654 SoC Gigabit
Ethernet two ports Switch subsystem (CPSW NUSS).
