ASoC: soc-dapm: add snd_soc_dapm_to_dev()

Browse Source 
Because struct snd_soc_dapm_context is soc-dapm framework specific, user
driver don't need to access its member directly, we would like to hide
them. struct snd_soc_dapm_context will be removed from header in the
future.

Some drivers need to get dev from dapm (which will be removed).
We need such function. Add it.
