Jasvinder Singh 947024a26d examples/ip_pipeline: rework passthrough pipeline
Passthrough pipeline implementation is split to two files.
pipeline_passthrough.c file handles front-end functions (cli commands
parsing) pipeline_passthrough_ops.c contains implementation of functions
done by pipeline (back-end).
