Add the required 'mboxes' property to both the C66x DSP processors on 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 R5Fs. 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.
