[PATCH 08/15] ASoC: SOF: ipc: Separate the ops checks by functions/topics

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi at linux.intel.com>

Separate the mandatory ops checks by topics (pcm and topology for now) to
be able to provide intuitive feedback on the possible missing ops and to
make it easier to add new mandatory ops checks in the future.
