[PATCH 02/19] ASoC: add soc-card.c

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

Current ALSA SoC has some snd_soc_card_xxx() functions,
and card->xxx() callbacks.
But, it is implemented randomly at random place.

To collect all card related functions into one place,
this patch creats new soc-card.c.
