No code change. Just code move from hda_link_dma_params() to hda_link_dma_hw_params().

Remove the trigger_suspend_stop argument from hda_link_dma_cleanup() and move the call to snd_hdac_ext_stream_clear() into snd_hdac_ext_stream_clear(). This is a preparatory step to unify the trigger ops for IPC3 and IPC4.

From: Ranjani Sridharan ranjani.sridharan@linux.intel.com

Define the post_trigger DMA op for IPC3 and unify the DAI driver ops for IPC3 and IPC4 for HDA DAI's.

Also, use the post_trigger op to stop the paused streams properly in the hda_dai_suspend() function. This fixes the suspend while paused case for IPC4 because previously we weren't resetting the pipeline when suspending the system with some paused streams.
