Add the DT node for this DSP processor sub-system. The processor does not have a MMU, and uses various IPC Generation registers and shared memory for inter-processor communication. The alias with a stem 'rproc' has also been added for the DSP, it provides a fixed remoteproc id for the DSP processor. Signed-off-by: Suman Anna Signed-off-by: Sam Nelson Signed-off-by: Andrew F.
