Reserve those at board level DT to avoid remote processor crashes. While at it, switch the MAIN domain R5F cluster into split mode to maximize the number of R5F processors. The TI IPC firmware for the split processors is already available public. This config aligns with other J721E boards and can be refactored out later.
