ASoC: SOF: Intel: hda: Introduce HDA DAI abstraction

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

This series introduces an abstraction of the HDA DAI handling.

The motivation is to simplify and make the code more flexible regarding to IPC
versions, new features (ChainDMA (IPC4) and DSPless mode) and to pave the way for new
platforms.

For the first look the series might feels a bit too intrusive but it introduces
no functionality change (tested at each commit).
