From: Bard Liao yung-chuan.liao@linux.intel.com
sof_ipc4_dma_config_tlv{} is required for ACE2.x. The patch follow the convention to set the dma_stream_channel_map.mapping device as "link_id << 8 | pdi_id". And the mapping in sof_ipc4_alh_configuration_blob{} should be the same as dma_stream_channel_map.mapping in sof_ipc4_dma_config{}. The purposes of device id is to map DMA tlv.
