ASoC: soc-core: add NOTE to snd_soc_rtdcom_lookup()
We can find specified name component via snd_soc_rtdcom_lookup().
But, it is not enough under multi CPU/Codec/Platform, because many
components which have same driver name might be connected to same rtd.

Not using this function as much as possible is best solution,
but some drivers are already deeply depended to it.

We can expand this function, for example having "num" which specifies
found order at parameter, etc (In such case, it need to have fixed
probing order).
Or, use different driver name in such component, etc.

We will have such issue if multi CPU/Codec/Platform were supported.
To indicate it, this patch adds NOTE to this function.

ASoC: soc-core: use device_register()
It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.

soc-core.c is using device_unregiser(), but there is no its paired
device_regiser(). We can find its code at soc_post_component_init()
which is using device_initialize() and device_add().
Here, device_initialize() + device_add() = device_register().

	-- linux/drivers/base/core.c --
	int device_register(struct device *dev)
	{
		device_initialize(dev);
		return device_add(dev);
	}

device_initialize() is doing each dev member's initialization only,
not related to device parent/release/groups.
Thus, we can postpone it.
let's use device_register() instead of device_initialize()/device_add().

ASoC: soc-core: remove unneeded dai_link check from snd_soc_remove_dai_link()
snd_soc_remove_dai_link() has card connected dai_link check. but
	1) we need to call list_del() anyway,
	   because it is "remove" function,
	2) It is doing many thing for this card / dai_link already
	   before checking dai_link.

This patch removes poinless dai_link check

ASoC: core: Move pcm_mutex up to card level from snd_soc_pcm_runtime
The pcm_mutex is used to prevent concurrent execution of snd_pcm_ops
callbacks. This works fine most of the cases but it can not handle setups
when the same DAI is used by different rtd, for example:
pcm3168a have two DAIs: one for Playback and one for Capture.
If the codec is connected to a single CPU DAI we need to have two dai_link
to support both playback and capture.

In this case the snd_pcm_ops callbacks can be executed in parallel causing
unexpected races in DAI drivers.

By moving the pcm_mutex up to card level this can be solved
while - hopefully - not breaking other setups.

ASoC: soc-core: support snd_soc_dai_link_component for aux_dev
To find aux_dev, ASoC is using .name, codec_name, codec_of_node.
Here, .name is used to fallback in case of no codec.

But, we already have this kind of component finding method by
snd_soc_dai_link_component and soc_find_component().
We shouldn't have duplicated implementation to do same things.
This patch adds snd_soc_dai_link_component support to finding aux_dev.

Now, no driver is using only .name.
All drivers are using codec_name and/or codec_of_node.
This means no driver is finding component from .name so far.
(Actually almost all drivers are using .name as just "device name",
 not for finding component...)

This patch
1) add snd_soc_dai_link_component support for aux_dev. legacy style will
   be removed if all drivers are switched to new style.
2) try to find component via snd_soc_dai_link_component.
   Then, it doesn't try to find via .name, because no driver is using
   it so far.

ASoC: soc-component: add snd_soc_component_get/put()
ALSA SoC is calling try_module_get()/module_put() based on

To keep simple and readable code, we should create its function.
This patch adds new snd_soc_component_get/put().

ASoC: add soc-component.c
ALSA SoC has many snd_soc_component_xxx(), but these are randomly
located in many files. Because of it, code is difficult to read.
This patch creates new soc-component.c, and moves existing
snd_soc_component_xxx() into it.
But not yet fully. We need more cleanup it.

ASoC: core: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Also, there is no need to store the individual debugfs file name, just
remove the whole directory all at once, saving a local variable.

Note, the soc-pcm "state" file has now moved to a subdirectory, as it is
only a good idea to save the dentries for debugfs directories, not
individual files, as the individual file debugfs functions are changing
to not return a dentry.

ASoC: create pcm for codec2codec links as well
At the moment, codec to codec links uses an ephemeral variable for
the struct snd_pcm_substream. Also the struct snd_soc_pcm_runtime
does not have real struct snd_pcm.

This might a problem if the functions used by a codec on codec to
codec link expect these structures to exist, and keep on existing
during the life of the codec.

For example, it is the case of the hdmi-codec, which uses
snd_pcm_add_chmap_ctls(). For the controls to works, the pcm and
substream must to exist.

This change is first step, it create pcm (and substreams) for codec
to codec links, in the same way as dpcm backend links.

ASoC: add soc-dai.c
Current ALSA SoC has many snd_soc_dai_xxx() function which is
using dai->driver->ops->xxx.
But, some of them are implemented as snd_soc_dai_xxx(),
but others are directly using dai->driver->ops->xxx.
Because of it, the code is not easy to read.

This patch creats new soc-dai.c and moves snd_soc_dai_xxx()
functions into it.
One exception is snd_soc_dai_is_dummy() which is based on
soc-utils local variable. We need to keep it as-is there.

Others which is directly using dai->driver->ops->xxx will be
implemented at soc-dai.c by incremental patches.

ASoC: soc-core: support dai_link with platforms_num != 1
Add support platforms_num != 1 in dai_link. Initially, the main purpose of
this change was to make the platform optional in the dai_link, instead of
inserting the dummy platform driver.

This particular case had just been solved by Kuninori Morimoto with
commit 1d76898928 ("ASoC: soc-core: allow no Platform on dai_link").

However, this change may still be useful for those who need multiple
platform components on a single dai_link (it solves one of the FIXME
note in soc-core)
