C6x DSP nodes defined in the top-level J721e SoC dtsi files are incomplete and will not be functional unless they are extended with both mboxes and memory-region information. As theses only known about at the board integration level, these nodes should only be enabled when provided with this information. Disable the C6x DSP nodes in the dtsi files and only enable the ones that are given the required mboxes and memory-region on a given board.
