remoteproc: k3-r5: Refactor Data Structures to Align with DSP and M4

Currently, struct members such as mem, num_mems, reset, tsp, ti_sci and
ti_sci_id are part of the k3_r5_core structure. To align the rproc->priv
data structure of the R5 remote processor with that of the DSP and M4,
move the above members from k3_r5_core to k3_r5_rproc struct.

Additionally, introduce a void *priv pointer in k3_r5_rproc that can be
typecasted to point to the k3_r5_core structure. This abstraction is
done to ensure common functionalities across R5, DSP and M4 drivers can
be refactored at a later stage.
