Subject: [RFC PATCH 1/3] pcm: use substream instead of runtime in snd_pcm_hw_rule_add()

Replace struct snd_pcm_runtime *runtime with struct snd_pcm_substream
*substream in the header of snd_pcm_hw_rule_add(). This will allow us to
use a different struct snd_pcm_hw_constraints later, for BEs. The drivers
that call snd_pcm_hw_rule_add() and its wrappers are also updated.
