Subject: [PATCH v4 4/5] arm64: dts: ti: k3-j721e: disable "mcu_cpsw" in SoC file and enable it 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-j721e-mcu-wakeup.dtsi" and enable it in the board
files:
a) k3-j721e-beagleboneai64.dts
b) k3-j721e-common-proc-board.dts
c) k3-j721e-sk.dts
