[PATCH v2 01/39] ASoC: soc-dai.h: merge DAI call back functions into ops

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

snd_soc_dai_driver has .ops for call back functions (A), but it also
has other call back functions (B). It is duplicated and confusable.

	struct snd_soc_dai_driver {
		...
 ^		int (*probe)(...);
 |		int (*remove)(...);
(B)		int (*compress_new)(...);
 |		int (*pcm_new)(...);
 v		...
(A)		const struct snd_soc_dai_ops *ops;
		...
	}

This patch merges (B) into (A).
