ASoC: convert asoc_xxx() to snd_soc_xxx()

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

ASoC is using 2 type of prefix (asoc_xxx() vs snd_soc_xxx()), but there
is no particular reason about that [1].
To reduce confusing, standarding these to snd_soc_xxx() is sensible.

This patch adds asoc_xxx() macro to keep compatible for a while.
It will be removed if all drivers were switched to new style.
