ASoC: SOF: Intel: hda: Unify DAI drv ops for IPC3 and IPC4 

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.
