commit 900dedd7 ("ASoC: Introduce snd_soc_of_get_dai_link_cpus")
adds new snd_soc_of_get_dai_link_cpus(), but it is using
"codec" everywhere. It is very strange, and is issue when error case.
It should call cpu instead of codec in error case.
This patch tidyup it.

Now all the drivers are updated to have the new legacy_dai_naming
flag, update the core code so it also uses the new flag. Paving
the way for the old non_legacy_dai_naming flag to be removed.

It should be noted this patch will affect the CODEC drivers that don't
specify the non_legacy_dai_naming flag. These drivers will update from
using legacy DAI naming to the new scheme after this patch, this is
being considered a fix as the intention was for all CODEC drivers to use
the new scheme and all existing CODEC drivers were updated to do so
before componentisation. This just corrects those devices that have
snuck in since componentisation. The corrected devices are as
follows:

adau1372, cros_ec_codec, cs35l41, cs35l45, cx2072x, hdac_hda,
jz4725/60/70, lpass-rx/tx/va/wsa-macro, max98504, max9877,
mt6351/58/59, mt6660, pcm3060, rk3328, rt1308/16, rt5514,
rt5677, rt700/11/15, rt9120, sdw-mockup, tlv320adc3xxx, tscs454,
wcd9335/4x/8x, wsa881x

Some of these devices are used in some in kernel machine drivers,
however it appears all the usages use the actual DAI driver name
(since snd_soc_find_dai checks both the DAI name and the DAI driver
name). So it is not believed this change will break any in tree
machine drivers.

The new method is called just before the card is registered, providing
an opportune time for machine-level drivers to do some final controls
amending: deactivating individual controls or obtaining control
references for later use.

Some controls can be created by DAPM after 'late_probe' has been called,
hence the need for this new method.

All CPU drivers are now updated to accept a direct indication of
whether they are clock provider or consumer, rather than being told
if the CODEC is clock provider. As such update the core to always
pass this direct indication rather than only if the new set_fmt_new
callback is defined. Note this makes no difference to the CODEC
side of the DAI link as it was already being directly told if it
was clock provider under the old system.

The original set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. Now everything is
componentised it simplifies things if each side of the link is
just told if it is provider or consumer of the clocks. To start
this migration add a new callback that can be used to receive a
direct specification of clocking. As there are more CODEC drivers
than platform drivers, we make the new flags identical to the old
CODEC flags meaning CODEC drivers will not require an update.

Passing the result of the helper function snd_soc_component_is_codec
to snd_soc_register_dai is less clear than just passing the DAI
naming flag directly. snd_soc_register_dai wants to know if it
should use the legacy DAI naming. The CODEC distinction is more
of a historical thing and not obviously directly related, and there
are already a couple of CPU side components that explicitly opt in
to non-legacy DAI naming.

In the case like dmaengine which's not a dai but as a component, the
num_dai is zero, dmaengine component has the same component_of_node
as cpu dai, when cpu dai component is not ready, but dmaengine component
is ready, try to get cpu dai name, the snd_soc_get_dai_name() return
-EINVAL, not -EPROBE_DEFER, that cause below error:

asoc-simple-card <card name>: parse error -22
asoc-simple-card: probe of <card name> failed with error -22

The sound card failed to probe.

So this patch fixes the issue above by skipping the zero num_dai

The existing locking for DPCM has several issues
a) a confusing mix of card->mutex and card->pcm_mutex.
b) a dpcm_lock spinlock added inconsistently and on paths that could
be recursively taken. The use of irqsave/irqrestore was also overkill.

The suggested model is:

1) The pcm_mutex is the top-most protection of BE links in the FE. The
pcm_mutex is applied always on either the top PCM callbacks or the
external call from DAPM, not taken in the internal functions.

2) the FE stream lock is taken in higher levels before invoking
dpcm_be_dai_trigger()

3) when adding and deleting a BE, both the pcm_mutex and FE stream
lock are taken.

ASoC is using dai_link which specify DAI format (= dai_link->dai_fmt),
and it is selected by "Sound Card" driver in corrent implementation.
In other words, Sound Card *needs* to setup it.
But, it should be possible to automatically selected from CPU and
Codec driver settings.

This patch adds new .auto_selectable_formats support
at snd_soc_dai_ops.

By this patch, dai_fmt can be automatically selected from each
driver if both CPU / Codec driver had it.
Automatically selectable *field* is depends on each drivers.

For example, some driver want to select format "automatically",
but want to select other fields "manually", because of complex limitation.
Or other example, in case of both CPU and Codec are possible to be
clock provider, but the quality was different.
In these case, user need/want to *manually* select each fields
from Sound Card driver.

This .auto_selectable_formats can set priority.
For example, no limitaion format can be HI priority,
supported but has picky limitation format can be next priority, etc.

It uses Sound Card specified fields preferentially, and try to select
non-specific fields from CPU and Codec driver automatically
if all drivers have .auto_selectable_formats.

In other words, we can select all dai_fmt via Sound Card driver
same as before.
