[ALSA] alsa core: add struct device pointer to struct snd_pcm

Browse Source 
This patch adds a struct device pointer to struct snd_pcm in order to be
able to give it a different device than the card. It defaults to the card's
device, however, so it should behave identically for drivers not touching
the field.
