[PATCH v2 002/186] ASoC: ac97: replace codec to component

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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

Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 0	->	.idle_bias_on = 1
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1

To keep compatibilty, this patch adds snd_soc_xxx_ac97_codec()
macro. These will be removed when all codec code was removed.
