Add the DT nodes for these DSP processor sub-systems. The processors do not have an MMU, and use various IPC Generation registers and shared memory for inter-processor communication. The aliases with a stem 'rproc' have also been added for all the DSPs, they provide a fixed remoteproc id to each DSP processor.
