[PATCH 10/13] ASoC: add snd_soc_component_read32

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

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

Current codec drivers are using snd_soc_read(). It will be replaced
into snd_soc_component_read(), but these 2 are using different style.
For example, it will be

	- val = snd_soc_read(xxx, reg);
	+ ret = snd_soc_component_read(xxx, reg, &val);
	+ if (ret < 0) {
	+	...
	+ }

To more smooth replace, let's add snd_soc_component_read32

	- val = snd_soc_read(xxx, reg);
	+ val = snd_soc_component_read32(xxx, reg);
