Add the DT node for this DSP processor sub-system. The DT node has a new property 'power-domains' and no 'clocks' properties, and uses slightly different property values for 'resets' compared to other Keystone 2 SoCs. The processor does not have an 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: Andrew F.
