[PATCH 01/18] ASoC: SOF: Introduce struct snd_sof_dai_link

[Ranjani Sridharan <ranjani.sridharan@linux.intel.com>]

Introduce a new struct for DAI links to save the DAI link information
parsed from topology. Also add a list of dai_links to struct snd_sof_dev
that will be populated during topology parsing.
