Add the required 'mboxes' property to the C71x DSP processor for the TI J721E common processor board. The mailboxes and some shared memory are required for running the Remote Processor Messaging (RPMsg) stack between the host processor and each of the DSPs. The nodes are therefore added in the common k3-j721e-som-p0.dtsi file so that all of these can be co-located. The chosen sub-mailboxes match the values used in the current firmware images. This can be changed, if needed, as per the system integration needs after making appropriate changes on the firmware side as well.
