ASoC: Vendor drivers get a link's runtime by snd_soc_get_pcm_runtime()

Vendor drivers no longer access a DAI link's runtime by the link index
but by matching the link name via snd_soc_get_pcm_runtime(). We assume
each DAI link has a unique name.

This is preparation for changing runtimes from an array to a list later.
