Add mtk_soundcard_pdata platform data for the MediaTek common sound card
probe mechanism, including a driver/soc-specific probe extension (used
for bits that cannot be commonized hence specific to this driver), and
change the probe function to mtk_soundcard_common_probe.
This is also adding the possibility of specifying the links and routing
with the audio-routing property and (x)-dai-link nodes in device trees
to stop hardcoding machine specific links in the card driver assupported
by the common probe function, but support for legacy device trees is
retained with a legacy_probe function, which is used only in case the
new properties are not found.

Apart from a dai_link_list variable, the mtk_sof_priv currently holds
data that never gets modified during runtime.
Constify the mtk_sof_priv structure and move the SOF dai_link_list as
sof_dai_link_list in struct mtk_soc_card_data, which is a structure
that already holds the card's machine specific, runtime modified data.
This allows to safely pass the mtk_sof_priv structure as platform data
for the commonized card probe mechanism.

Add a common machine soundcard driver probe function that supports both
DSP and AFE-direct usecases and also provides a hook for legacy machine
soundcard driver probe mechanisms.
Note that the hook is there because, even for legacy probe, a lot of the
actual code can still be commonized, hence still reducing duplication
for the legacy devicetree retrocompatibility cases.
This common probe function deprecates all of the inconsistent previous
probe mechanisms and aims to settle all of the MediaTek card drivers on
consistent and common devicetree properties describing wanted DAIs,
device specific DAI configuration and DAI links to codecs found on
each device/board.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
More cleanups from Brent, notably the removal of the redundant
cml_rt1011_rt5682 machine driver, fixes for SoundWire platforms and
changes to sof_rt5682 to allow for 96+ sampling rates.
For the rest of this kernel cycle, we are still working on SoundWire
updates for MeteorLake (usual missing ACPI signature required for
topology selection and jack detection information). We'll provide
those patches as soon as they are reviewed/validated.
This patch removes a confusion between speakers and amplifiers.
The existing code keeps track of the number of amplifiers and reports
it in the 'cfg-amp' component string.
The number of speakers is defined with quirks, but those quirks are
not consistently added: in the MeteorLake case, none of the supported
platforms used such a quirk, and UCM does not use the values reported
anyways. The notion of 'FOUR_SPEAKERS' is also obsolete now with some
platforms having more than four speakers.
Let's just remove all this and only report the number of amplifiers.

This series aims to add some features to McBSP driver.
Convert bindings from .txt to .yaml.
Add possibility to use an external clock as sample rate generator's
input.
Add handling of new formats (TDM, S24_LE, BP_FC).
Enable the detection of unexpected frame pulses.
Set the clock free-running mode according to SND_SOC_DAIFMT_[GATED/CONT]
configuration in DAI format.
Add ti,T1-framing[tx/rx] properties in DT. They allow to set the data
delay to two bit-clock periods.
This has been tested on a platform designed off of the DAVINCI/OMAP-L138
connected to 3 daisy-chained AD7767. An external clock drives the
sample rate generator through the CLKS pin.
The hardware I have only allowed me to test acquisition side of McBSP.
It is connected to a 6 channels TDM and acts as Bit clock provider and
Frame clock consumer.

McBSP's data delay can be configured from 0 to 2 bit clock periods. 0 is
used for DSP_B format, 1 is used for DSP_A format, 2 is unused.
A data delay of 2 bit clock periods can be used to interface to
'T1 framing' devices where data stream is preceded by a 'framing bit'. On
transmission, McBSP inserts a blank period (high-impedance period)
before the first data bit to leave an opportunity for other devices to
set this 'framing bit'. On reception, McBSP discards the 'framing bit'
that precedes the data stream.
Add support for the 'framing bit' according to the
'ti,T1-framing-[tx/rx]' device-tree properties. If a flag is present,
the data delay is set to 2 bit clock periods regardless of the selected
DAI format.

TDM is not supported by the McBSP driver. The McBSP datasheet does not
name explicitly TDM as a supported format but it is possible to configure
the McBSP to do TDM if all slots are used by McBSP.
Add TDM support. It uses single-phase frame. Slot width is used to
compute the McBSP's word length.
Implement the set_tdm_slot() hook of snd_soc_dai_ops struct. It only
supports TDM if all slots are used by McBSP.
The snd_soc_dai_driver's channels_max is updated from 2 to 128.
This was tested with BP_FC format on a platform designed off of
DAVINCI/OMAP_L138. A check is done in davinci_i2s_set_dai_fmt() to
prevent TDM to be used with BC_FC and BC_FP formats.

McBSP's internal sample rate generator can be programed to be driven by
its internal clock or by an external clock source located on CLKS pin.
The external clock source case is not handled by the driver.
Handle an optional clock related to this external clock source. If
present, the driver uses the clock located on CLKS pin as input for the
sample rate generator. Thus, the external clock rate is used to compute
divisors. If this optional clock is not present, the sample rate
generator is driven by the McBSP's functional clock.

Remove the attribute.
Keep the behaviour of the MCBSP_CLKR case as MCBSP_CLKR == 0.
I can't test the BC_FP format so I added back the initial comment that
was removed by commit ec63755337 ("ASoC: DaVinci: Added selection of
