ASoC: amd: ps: Fix extraneous error messages

On Pink Sardine machines that don't have SdW controllers in use, the property
`mipi-sdw-manager-list` won't exist.  There is no point in showing an error
to a user when this situation is encountered.

Furthermore if the machine doesn't have a DMIC connected to the ACP, there
may be no platform devices created either.

Downgrade the associated message to debug.
