The core's internal memory data structure will be refactored to be part
of the k3_r5_rproc structure in a future commit. As a result, internal
memory initialization will need to be performed inside
k3_r5_cluster_rproc_init() after rproc_alloc().
Therefore, move the internal memory initialization function,
k3_r5_core_of_get_internal_memories() above k3_r5_rproc_init() so that
it can be invoked from there.
