Subject: [PATCH] ASoC: SOF: Intel: Expose SDnFMT helpers
Git-commit: 49d7948ed174cc170041bf3d22e1f085fd8b87f0
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518

Hda stream is setup in similar fashion for compress as it is for pcm
operations. To reuse existing code in compress path, expose SDnFMT
helper routines.
