ALSA SoC need to care pinctrl_pm_select_xxx().
It is called at soc-core and soc-pcm.
soc-pcm is controlling it for activate DAI.
soc-core is controlling it for whole system
(= suspend/resume/probe/poweroff).
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);
(b) pinctrl_pm_select_xxx(dai->dev, xxx);
Because of these unbalance, the code is confusable.
Here, dai->dev and component->dev are same pointer.
Thus, we can replace it component base.
One note here is that it cared DAI (= CPU/Codec) pin before this patch,
after this patch, it cares Component (= CPU/Codec/Platform) pin.

(1) is called for all component (CPU/Codec/Platform), and
(2) is called for CPU DAIs.
Here, component->dev is same as dai->dev.
This means, it is called in duplicate on CPU case.
This patch removes (2).

Card dai_link has .ignore_suspend, and ALSA SoC cares it when suspend.
For example, like this
for_each_card_rtds(card, rtd) {
if (rtd->dai_link->ignore_suspend)
continue;
...
}
But in snd_soc_suspend(), it doesn't care about
it when suspending Component. This patch cares it.

Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.
struct snd_soc_rtdcom_list {
struct snd_soc_component *component;
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 */
rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus);
...
(a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component);
...
/* Find CODEC from registered CODECs */
(b) for_each_link_codecs(dai_link, i, codec) {
rtd->codec_dais[i] = snd_soc_find_dai(codec);
...
(a) snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component);
}
...

(b) for_each_link_platforms(dai_link, i, platform) {
for_each_component(component) {
...
(a) snd_soc_rtdcom_add(rtd, component);
}
}
}
It shows, it is possible to know how many components will be
connected to rtd by using
dai_link->num_cpus
dai_link->num_codecs
dai_link->num_platforms
If so, we can use component pointer array instead of list_head,
in such case, code can be more simple.
This patch removes struct snd_soc_rtdcom_list that is only
of temporary value, and convert to pointer array.

Use our default values when wrong module-parameters are given, instead of

case.
