ALSA: pcm: Embed struct device
Like previous patches, at this time we embed the struct device into PCM object. However, this needs a bit more caution: struct snd_pcm doesn't own one device but two, for both playback and capture! Thus not struct snd_pcm but struct snd_pcm_str object contains the device. Along with this change, pcm->dev field is dropped for avoiding confusion. It was meant to point to a non-standard parent. But, since now we can touch each struct device directly, we can manipulate the parent field easily there, too.
