ASoC: SOF: ipc4-topology: Save the ALH DAI index during hw_params

Browse source

The node_id for multi-gateway ALH DAI's get overwritten with the
group_id during the DAI copier's ipc_prepare op. So, save the ALH
dai_index during the BE DAI hw_params in the dai_index field of struct
ipc4_copier and use that to set the device ID in the configuration blob.
This will avoid errors during copier init after an xrun.

Note that the dai_index is typically set in topology for DMIC/SSP, but
it's not used for ALH. Reclaiming this dai_index field to store the
node_id does not generate a conflict with topology-defined values.
