ASoC: audio-graph: respawn Platform Support
commit 63f2f9cceb ("ASoC: audio-graph: remove Platform support")
removed Platform support from audio-graph, because it doesn't have
"plat" support on DT (simple-card has).
But, Platform support is needed if user is using
snd_dmaengine_pcm_register() which adds generic DMA as Platform.
And this Platform dev is using CPU dev.

Without this patch, at least STM32MP15 audio sound card is no more
functional (v5.13 or later). This patch respawn Platform Support on
audio-graph again.

ASoC: audio-graph: tidyup graph_parse_node()
audio-graph is using cpus->dai_name / codecs->dai_name for
dailink->name.
In graph_parse_node(), xxx->dai_name is got by
snd_soc_get_dai_name(), but it might be removed soon by
asoc_simple_canonicalize_cpu().

The order should be
	*1) call snd_soc_get_dai_name()
	 2) create dailink name
	*3) call asoc_simple_canonicalize_cpu()

* are implemented in graph_parse_node().
This patch remove 3) from graph_parse_node()

ASoC: audio-graph: remove Platform support
Platform was one of mandatory component on ASoC before,
and audio-graph-card was assuming that CPU and Platform were
same driver.

But it is no longer mandatory on ASoC.
Current ASoC will just ignore if Platform and CPU were same
or doplicated component.

Of course ASoC is supporting Platform, but current
audio-graph-card doesn't support detecting it from DT.

This means current audio-graph-card operation for Platform so far
is 100% useless. This patch removes it.
We can respawn it when we need it.

ASoC: simple-card-utils: Propagate errors on too many links
The DAI counting code doesn't propagate errors when the number of
maximum links is exceeded, which causes subsequent initialization code
to continue to run and that eventually leads to memory corruption with
the code trying to access memory that is out of bounds.

Fix this by propagating errors when the maximum number of links is
reached, which ensures that the driver fails to load and prevents the
memory corruption.

Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec

I beliave it can contribute to reduce memory.

By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(),
thus, its settings are no longer needed at DPCM detecting timing

ASoC: audio-graph: Expose helpers from audio graph
This commit exposes following functions which can be used by a sound
card driver based on generic audio graph driver. Idea is vendors can
have a thin driver and re-use common stuff from audio graph driver.

 - graph_card_probe()
 - graph_parse_of()

In doing so a new header file is added for above. The graph_probe()
function is simplified by moving more common stuff to graph_parse_of().

ASoC: audio-graph: Expose new members for asoc_simple_priv
Add new members in struct 'asoc_simple_priv'. Idea is to leverage
simple or graph card driver as much as possible and vendor can
maintain a thin driver to control the behavior by populating these
newly exposed members.

Following are the members added in 'asoc_simple_priv':

  - 'ops' struct: In some cases SoC vendor drivers may want to
    implement 'snd_soc_ops' callbacks differently. In such cases
    custom callbacks would be used.

  - 'force_dpcm' flag: Right now simple or graph card drivers
    detect DAI links as DPCM links if:

      * The dpcm_selectable is set AND
      * Codec is connected to multiple CPU endpoints or aconvert
        property is used for rate/channels.

    So there is no way to directly specify usage of DPCM alone. So a
    flag is exposed to mark all links as DPCM. Vendor driver can
    set this if required.

  - 'dpcm_selectable': Currently simple or audio graph drivers
    provide a way to enable this for specific compatibles. However
    vendor driver may want to define some additional info. Thus
    expose this variable where vendor drivers can set this if
    required.

Audio graph driver is updated to consider above flags or callbacks.
Subsequent patches in the series illustrate usage for above.

endpoint is not fixed always. It actually depends on the compatible
HW module that is going to be connected. From SoC side the given I/O
interface is always available. Hence such links have fixed CPU endpoint
but no Codec endpoint. This patch helps to support such links where
user can populate Codec endpoint only and its fields in Platform DT
depending on the plugged HW.

ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM
PCM devices are created for FE dai links with 'no-pcm' flag as '0'.
Such DAI links have CPU component which implement either pcm_construct()
or pcm_new() at component or dai level respectively. Based on this,
current patch exposes a helper function to identify such components
and populate 'no_pcm' flag for DPCM DAI link.

This helps to have BE<->BE component links where PCM devices need
not be created for CPU component involved in such links.

ASoC: audio-graph: Use of_node and DAI for DPCM DAI link names
For multiple instances of components, using DAI name alone for DAI links
is causing conflicts. Components can define multiple DAIs and hence using
just a device name won't help either. Thus DT device node reference and
DAI names are used to uniquely represent DAI link names.

ASoC: soc-dai: set dai_link dpcm_ flags with a helper
Add a helper to walk through all the DAIs and set dpcm_playback and
dpcm_capture flags based on the DAIs capabilities, and use this helper
to avoid setting these flags arbitrarily in generic cards.

The commit referenced in the Fixes tag did not introduce the
configuration issue but will prevent the card from probing when
detecting invalid configurations.

ASoC: audio-graph: indicate rebind issue
ALSA SoC try to rebind Sound Card if Card/CPU/Codec/Platform
were unbinded and re-binded again.
But, Audio Graph Card might can't rebind again if user do for example

	unbind CPU or Codec driver
	bind   CPU or Codec driver

Because Audio Graph Card is still pointing old/unbinded
CPU or Codec driver's DAI name at dlc->dai_name.

To avoid this issue, it needs to alloc memory and keep DAI name
even though if CPU or Codec driver was unbinded.
Or, always do unbind/bind at Sound Card.

For now, this patch indicates this issue as FIXME.

ASoC: audio-graph-card: don't select DPCM via audio-graph-card
commit ae3cb57909 ("ASoC: audio-graph-card: merge
audio-graph-scu-card") merged audio-graph-scu-card which can
handle DPCM into audio-graph-card.

By this patch, the judgement to select "normal sound card" or
"DPCM sound card" is based on its OF-graph endpoint connection.
But, because of it, existing "audio-graph-card" user who is
assuming "normal sound card" might select DPCM unintentionally.

To solve this issue, this patch allows "audio-graph-card" user
can select "normal sound card", and "audio-graph-scu-card" user
can select both "normal sound card" and "DPCM sound card".
This keeps compatibility collectry.
