arm: dts: k3-j721e: Add initial support for common processor board
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. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
