ASoC: ak4613: Improve counting DAI number
Add the startup function to count DAI instead of hw_params.
This change matches the number of opened DAIs.
If this change isn't applied, you may get unexpected error due to
mismatching of count. Since the excution number of hw_params and
shutdown may be different, the mismatching happens.
