[U-Boot] [PATCH v3 13/16] arm: dts: k3-j721e: Add initial support for common processor board

[Lokesh Vutla]

Common Processor board is the baseboard that has most of the actual connectors,
power supply etc. A SOM (System on Module) is plugged on to the common
processor board and this contains the SoC, PMIC, DDR and basic highspeed
components necessary for functionality. Add initial dt support for this
common processor board.
