ASoC: Implement DAI links in a list & define API to add/remove a link
Implement a dai link list for the soc card.
Add APIs to add/remove a DAI links dynamically, e.g. by topology.
And a dobj is embedded into the struct snd_soc_dai_link. Topology can
use the dobj to find the links created by it and remove them when the
topology component is unloaded.
The predefined DAI links are reserved to keep backward compatibility.
And they will also be added to the list.
