ASoC: SOF: Intel: hda-dai: set dma_stream_channel_map device
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.
