ASoC: soc-core: add .num_platform for dai_link
Current snd_soc_dai_link is starting to use snd_soc_dai_link_component
(= modern) style for Platform, but it is still assuming single Platform
so far. We will need to have multi Platform support in the not far
future.
Currently only simple card is using it as sound card driver,
and other drivers are converted to it from legacy style by
snd_soc_init_platform().
To avoid future problem of multi Platform support, let's add
num_platforms before it is too late.
In the same time, to make it same naming mothed, "platform" should
be "platforms". This patch fixup it too.

ASoC: simple-card: support snd_soc_dai_link_component style for platform
Current ASoC is supporting snd_soc_dai_link_component for binding,
it is more useful than current legacy style.
Currently only codec is supporting it as multicodec (= codecs).
CPU will support multi style in the future.
We want to have it on Platform too in the future.
If all Codec/CPU/Platform are replaced into snd_soc_dai_link_component
style, we can remove legacy complex style.
This patch supports snd_soc_dai_link_component style
for simple-card for platform.

ASoC: soc-pcm: merge playback/cature_active into stream_active
DAI has playback_active and capture_active to care usage count.
OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE.
But because of this kind of implementation mismatch,
ALSA SoC has many verbose code.
To solve this issue, this patch merge playback_active/capture_active
into stream_active[2];

ASoC: simple-card-utils: separate asoc_simple_card_parse_dai()
The difference between simple-card / audio-graph are just using
OF graph style, or not. In other words, other things should be same.
This means, simple-card/audio-graph common functions should be
implemented at simple-card-utils, and its own functions should be
implemented at each files.
Current simple-card / audio-graph are using
asoc_simple_card_parse_dai() which is different implementation.
But, these are implemanted at simple-card-utils.
It should be implemanted at each files.
This patch separate these into each files.

ASoC: simple-card: rename to asoc_simple_card_canonicalize_platform()
Current simple-card is using asoc_simple_card_canonicalize_dailink().
Its naming is "dailink", but is for "platform".
We already have asoc_simple_card_canonicalize_cpu() for "cpu",
let's follow same naming rule.
It never return error, so, void function is better idea.

ASoC: simple-card-utils: rename asoc_simple_card_xxx() to asoc_simple_()
Currently, installation is only supported on real hardware, but not
running in QEMU. Change the check to make sure the necessary
directories and programs are available instead of bailing out
on non-Raspberry archs.
