ALSA SoC is currently categorizing CPU/Codec DAIs,

But modern devices require more complex connections,
for example Codec to Codec, etc, and future devices will
enable to more complex connections.
Because of these background, CPU/Codec DAIs categorizing is
no longer good much to modern device.

Currently, rtd has both CPU/Codec DAIs pointer.

	rtd->cpu_dais   = [][][][][][][][][]
	rtd->codec_dais = [][][][][][][][][]

This patch merges these into DAIs pointer.

This reverts commit b2354e40.

This change might have been desirable to ensure the uniqueness of
the component name. It would have helped to better support linux
devices which register multiple components, something is which more
common than initially thought.

However, some card driver are directly using dev_name() to fill the
component names of the dai_link which is a problem if want to change
the way ASoC generates the component names.

Until we figure out the appropriate way to deal with this, revert the
change and keep the names as they were. There might be a couple of warning
related to debugfs (which were already present before the change) but it
is still better than breaking working audio cards.

Historically, CPU and Codec were implemented different, but now it is
merged as Component.
ALSA SoC is supporting suspend/resume at DAI and Component level.
The method is like below.

	1) Suspend/Resume all CPU DAI if bus-control was 0
	2) Suspend/Resume all Component
	3) Suspend/Resume all CPU DAI if bus-control was 1

Historically 2) was Codec special operation.
Because CPU and Codec were merged into Component,
CPU   suspend/resume has 3 chance to suspend(= 1/2/3), but
Codec suspend/resume has 1 chance (= 2).

Here, DAI side suspend/resume is caring bus-control, but no driver
which is supporting suspend/resume is setting bus-control.
This means 3) was never used.

Here, used parameter for suspend/resume component->dev and dai->dev are
same pointer.
For that reason, we can merge DAI and Component suspend/resume.
One note is that we should use 2), because it is caring BIAS level.

This patch removes 1) and 3).

soc-pcm  is controlling it for activate DAI.
soc-core is controlling it for whole system

If we focus to soc-core side, it need to care about BIAS level.
Then, snd_soc_suspend() only is controlling it by Component base (a).
Other functions are DAI base (b).

(a)	pinctrl_pm_select_xxx(component->dev, xxx);

Because of these unbalance, the code is confusable.
Here, dai->dev and component->dev are same pointer.

Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.

		struct list_head list; /* rtd::component_list */

	struct snd_soc_pcm_runtime {
		...
		struct list_head component_list; /* list of connected components */
		...

The CPU/Codec/Platform component which will be connected to rtd (a)
is indicated via dai_link at snd_soc_add_pcm_runtime()

	int snd_soc_add_pcm_runtime(...)
	{
		...
		/* Find CPU from registered CPUs */

It shows, it is possible to know how many components will be

To find codec_conf component, it is using dev_name, of_node.
But, we already has this kind of finding component method by
snd_soc_dai_link_component, and snd_soc_is_matching_component().
We shouldn't have duplicate implementation to do same things.
This patch adds snd_soc_dai_link_component support to find
codec_conf component.

Now all snd_soc_pcm_lib_ioctl() calls were dropped, and it became
superfluous.  Let's kill it.

soc-core.c has 2 #ifdef CONFIG_DMI, but we can merge these.
OTOH, soc.h has dmi_longname, but it is needed if CONFIG_DMI was defined.
In other words, It is not needed if CONFIG_DMI was not defined.
This patch tidyup these.
