ASoC: soc.h: convert asoc_xxx() to snd_soc_xxx()
ASoC is using 2 type of prefix (asoc_xxx() vs snd_soc_xxx()), but there
is no particular reason about that [1].
To reduce confusing, standarding these to snd_soc_xxx() is sensible.
This patch adds asoc_xxx() macro to keep compatible for a while.
It will be removed if all drivers were switched to new style.

ASoC: clarify Codec2Codec params
Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
ASoC is supporting Codec2Codec, but its parameter name is
"params" and "num_params" which are very unclear naming.
This patch-set clarifies it by replacing to c2c_params / num_c2c_params.

ASoC: soc-dai.h: cleanup Playback/Capture data for snd_soc_dai
Current snd_soc_dai has data for Playback/Capture, but it is very
random. Someone is array (A), someone is playback/capture (B),
and someone is tx/rx (C);
struct snd_soc_dai {
...
(A) unsigned int stream_active[SNDRV_PCM_STREAM_LAST + 1];
(B) struct snd_soc_dapm_widget *playback_widget;
(B) struct snd_soc_dapm_widget *capture_widget;
(B) void *playback_dma_data;
(B) void *capture_dma_data;
...
(C) unsigned int tx_mask;

};
Because of it, the code was very complicated.
This patch creates new data structure to merge these into one,
and tidyup the code.

ASoC: simple-card-utils: Move snd_soc_component_is_codec to be local
The helper function snd_soc_component_is_codec is based off the
presence of the non_legacy_dai_naming flag. This isn't super robust
as CPU side components may also specify this flag, and indeed the
kernel already contains a couple that do. After componentisation there
isn't really a totally robust solution to identifying what is a CODEC
driver, without introducing a flag specifically for that purpose, and
really the desirable direction to move in is that the distinction
doesn't matter.
This patch does two things to try to mitigate these problems. Firstly,
now that all the other users of the helper function have been removed,
it makes the helper function local to the driver rather, than being
part of the core. This should help to discourage any new code from
being created that depends on the CODEC driver distinction. Secondly,
it updates the helper function itself to use the endianness flag
rather than the non_legacy_dai_naming flag. The endianness flag is
definitely invalid on a CPU side component, so it a more reliable
indicator that the device is definitely a CODEC. The vast majority of
buses require the CODEC to set the endianness flag, so the number of
corner cases should be fairly minimal. It is worth noting that CODECs
sending audio over SPI, or built into the CPU CODECs are potential
corner cases, however the hope is that in most cases those types of
devices do not consitute a simple audio card.

ASoC: soc-pcm: Use different sequence for start/stop trigger
On stream stop currently we stop the DMA first followed by the CPU DAI.
This can cause underflow (playback) or overflow (capture) on the DAI side
as the DMA is no longer feeding data while the DAI is still active.
It can be observed easily if the DAI side does not have FIFO (or it is
disabled) to survive the time while the DMA is stopped, but still can
happen on relatively slow CPUs when relatively high sampling rate is used:
the FIFO is drained between the time the DMA is stopped and the DAI is
stopped.
It can only fixed by using different sequence within trigger for 'stop' and
'start':
case SNDRV_PCM_TRIGGER_START:
case SNDRV_PCM_TRIGGER_RESUME:
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
Trigger order: dai_link, DMA, CPU DAI then the codec
case SNDRV_PCM_TRIGGER_STOP:
case SNDRV_PCM_TRIGGER_SUSPEND:

ASoC: simple-card: Add support for codec2codec DAI links
Following the example in cb2cf0de1174 ("ASoC: soc-core: care Codec <->
Codec case by non_legacy_dai_naming"), determine if a DAI link contains
only codec DAIs by examining the non_legacy_dai_naming flag in each
DAI's component.
For now, we assume there is only one or a small set of valid PCM stream
parameters, so num_params == 1 is good enough. We also assume that the
same params are valid for all supported streams. params is set to the
subset of parameters common among all DAIs, and then the existing code
automatically chooses the highest quality of the remaining values when
the link is brought up.

Switch to snd_soc_dai_set_bclk_ratio
Replaces obsolete function snd_soc_dai_set_tdm_slot
The "sysclk = 24000000" value is supposed to come from the "clock-frequency"
field of ac108_mclk / ac10x_mclk, but somehow it isn't on 5.4 (vs 4.19). This
is a temporary work-around. For some strange unknown reasons, this affects
only the square 4-mic device, but not the linear 4-mic nor the 6-mics device.
The other two devices have two ac108's, and seem to work fine without it.
In v4.19:
seeed_voice_card_probe [snd_soc_seeed_voicecard]
-> devm_snd_soc_register_card [snd_soc_core]
-> snd_soc_register_card [snd_soc_core]
-> seeed_voice_card_dai_init [snd_soc_seeed_voicecard]
-> asoc_simple_card_init_dai [snd_soc_simple_card_utils]
-> snd_soc_dai_set_sysclk [snd_soc_core]
-> ac108_set_sysclk [snd_soc_ac108]
In 5.4:
seeed_voice_card_probe [snd_soc_seeed_voicecard]
-> devm_snd_soc_register_card [snd_soc_core]
-> snd_soc_register_card [snd_soc_core]
-> snd_soc_instantiate_card [snd_soc_core]
-> seeed_voice_card_dai_init [snd_soc_seeed_voicecard]
-> asoc_simple_init_dai.part.0 [snd_soc_seeed_voicecard]
-> snd_soc_dai_set_sysclk [snd_soc_core]
-> ac108_set_sysclk [snd_soc_ac108]
Which results in the "ac108_set_sysclk :24000000" kernel message.
Note the extra snd_soc_instantiate_card(), and the copied/renamed
asoc_simple_init_dai() - it became static and not-available to other drivers
in v5.x.

ASoC: simple-card: support snd_soc_dai_link_component style for codec
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 codec.
