Subject: [PATCH v3 3/5] arm64: dts: ti: k3-j7200: disable "mcu_cpsw" in SoC file and enable in board file

Following the existing convention of disabling nodes in the SoC file and
enabling only the required ones in the board file, disable "mcu_cpsw" node
in the SoC file "k3-j7200-mcu-wakeup.dtsi" and enable it in the board file
"k3-j7200-common-proc-board.dts".
