ASoC: SOF: ipc4-pcm: Pipe instances to dev_dbg in multi_pipeline_state()

Add a dev_dbg to sof_ipc4_set_multi_pipeline_state(). The debug print
lists the pipeline instance numbers that are included in the
SOF_IPC4_GLB_SET_PIPELINE_STATE message. Without this log its very
hard to tell what pipelines are affected. This print is very helpful
when analyzing SOF logs automatically.
