ASoC: SOF: Intel: hda-dai: add get_hlink callback
The existing code for HDAudio DAIs cannot be extended to other types
of DAIs, specific programming sequences need to be abstracted
away.
This patch hides the mechanism to determine the multi-link structure
related to the DAI and program the LOSIDV register. An added benefit
is that we can remove all references to the codec DAI from what should
be a CPU dai configuration only.
