[PATCH 02/17] Revert "ASoC: SOF: Intel: hda-dai-ops: reset device count for SoundWire DAIs"

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

From: Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>

This reverts commit 699e146d9ebf42ee2a5d4e4e28f7a49c4aef0105.
Don't reset device_count as we will use the multi-gateway firmware
configuration.
