Subject: [PATCH v3 0/5] TI-K3-DTS: Cleanup CPSW DT Nodes

Hello,

This series cleans up the CPSW Device-tree nodes by updating the SoC and
board files to keep CPSW disabled in the SoC files and enable it only in
the board files.

The following is a summary of the SoCs, CPSW instance and the Boards that
this series affects:

-----    -------    ----------------  --------------------------------------------
S.No.      SoC        CPSW Instance                    Board(s)
-----    -------    ----------------  --------------------------------------------
  1.       AM62          CPSW3G           AM625-Beagleplay, AM62-LP-SK, AM625-SK
  2.       AM65        MCU CPSW2G         AM654-Base-Board, IOT-2050 Based Boards
  3.       J7200       MCU CPSW2G         J7200-Common-Processor-Board
  4.       J721E       MCU CPSW2G         J721E-Common-Processor-Board
  5.       J721S2      MCU CPSW2G         AM68-SK-Base-Board, J721S2-Common-Processor-Board

Series is based on linux-next tagged next-20251010.

v2 of this series is at:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20250611114336.2392320-1-s-vadapalli@ti.com/
Changes since v2:
- Rebased series on next-20251010.
- In the first patch, the changes that were made within
  'k3-am625-sk.dts' in the previous version, have been
  moved into 'k3-am625-sk-common.dtsi'
- The 'status' property within 'nodes' has been ordered to follow:
  https://docs.kernel.org/devicetree/bindings/dts-coding-style.html#order-of-properties-in-device-node
