ASoC: SOF: ipc4-topology: change chain_dma handling in dai_config

Browse Source 
The chain_dma mode is currently only handled for HDaudio, but can be
used for orther DAIs starting with LunarLake. Move the chain_dma
handling earlier.

Error detection for the chain_dma case for older platforms is handled
at a different level.
