Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
When the audio started we print out here and there the Input and Output or only
the Input audio format for the module that is in path of the stream.
This is mostly OK but provides inconsistent an - in my opinion - hard to grasp
information.
The series reworks how the input/output format is selected and tries to improve
the consistency of the prints by applying universal rules:
- Module is not changing the format or it has only input or output and it has
single format on in and out side
Audio format for gain.1.1:
- Module is not changing the format or it has only input or output and it has
multiple formats on either in or out side
Audio format (in/out format index: 2/0) for host-copier.0.playback:
- Module is changing format then we print the input and output ones
- Input if it has single format
Input audio format for host-copier.0.capture:
- Input has multiple formats
Input audio format (format index: 0) for host-copier.0.playback:
Similar versions for the output format prints.
