[ Upstream commit 9822b4c90d77e3c6555fb21c459c4a61c6a8619f ]
For aggregated DAIs, the node ID is set to the group_id during the DAI widget's ipc_prepare op. With the current logic, setting the dai_index for node_id in the dai_config is redundant as it will be overwritten with the group_id anyway. Removing it will also prevent any accidental clearing/resetting of the group_id for aggregated DAIs due to the dai_config calls could that happen before the allocated group_id is freed.
