ASoC: SOF: Intel: hda-dai-ops: reset device count for SoundWire DAIs
The solution used before LunarLake relies on a 'Multi-gateway'
firmware configuration. This is no longer needed with the DMA hardware
handling multiple links directly. To avoid adding a platform-specific
quirk in the generic IPC4 code, this patch resets the device count
when fetching the stream context.
