Introduce a void pointer in the k3_{m4/dsp}_rproc internal data
structure which can be used to point to any private data needed by the
driver. Currently, the M4/DSP drivers do not have any private data, so
the pointer can be left pointing to NULL. Additionally, add a pointer to
the rproc struct within k3_m4_rproc internal struct. This is done to
align the data structures with R5 driver which can be factored out at a
later stage.
