Subject: [PATCH v2 2/5] arm64: dts: ti: k3-am65: 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-am65-mcu.dtsi" and enable it in the board file
"k3-am654-base-board.dts". Also, now that "mcu_cpsw" is disabled in the
SoC file, disabling it in "k3-am65-iot2050-common.dtsi" is no longer
required. Hence, remove the section corresponding to this change.

v1 of this patch was 3 different patches which have currently been
squashed:
 https://lore.kernel.org/r/20250529133443.1252293-6-s-vadapalli@ti.com/
 https://lore.kernel.org/r/20250529133443.1252293-7-s-vadapalli@ti.com/
 https://lore.kernel.org/r/20250529133443.1252293-8-s-vadapalli@ti.com/

Squashing the patches is the only change since the v1 series, in
addition to updating the commit message accordingly.

Regards,
Siddharth.
