Remove two machine descriptors which were added for development on
Intel RVPs but are no longer used or productized. This will not have
any impact on end-users. The corresponding cleanup was applied in the
SOF topologies.

2.25.1
SAMA7G5 includes an updated version of I2S-MCC, found previously on
SAM9X60. This controller includes 8 data pins, 4 for playback and 4 for
capture. For I2S and LEFT_J formats, these pins can be used to
send/receive up to 8 audio channels. For DSP_A, with TDM, any pins pair
(DIN/DOUT) from these 4 can be selected to send/receive data. This
version also includes 2 FIFOs (send and receive).
This patch set starts by moving the driver's bindings to yaml and
continues with adding a new compatible for the SAMA7G5 variant, followed
by the changes needed for I2S/LEFT_J support, TDM pin pair selection and
FIFO support, exclusively for SAMA7G5.
Changes in v2:
- moved DT binding conversion patch from the beginning to the end of the
patch serieses
- patches that update the DT binding are modified to change .txt file
instead of .yaml

2.27.0
The skylake driver disabled async suspend to prevent disabling
the DSP before the card was suspended during system suspend.
This code was carried over to the SOF driver. But, there is no
risk of the DSP getting disabled before the card is suspended
with the SOF driver. Therefore, it is safe to enable async suspend
and thereby optimize the system resume time.

It happens because the codec driver may probe prior to the imx gpio

The TGL RVP can be configured in many ways. We initially supported a
mixed configuration with RT711 in SoundWire mode and RT1308 in
TDM mode.
However Intel teams no longer have any hardware with this
configuration and there are no commercially-available devices using it
either, so let's remove this entry. The corresponding topology will
also be removed from the SOF tree.

SAMA7G5's I2S-MCC has 4 pairs of DIN/DOUT pins. Since TDM only uses a
single pair of pins for synchronous capture and playback, the controller
needs to be told which of the pair is connected. This can be mentioned
using the new "microchip,tdm-data-pair" property. The property is optional,
needed only if TDM is used, and if it's missing DIN/DOUT 0 pins will be
used by default.

Constify a number of static structs that are never modified in RealTek
codecs. The most important patches are the first two, which constifies
snd_soc_dai_ops and sdw_slave_ops, both which contain function pointers.
The other two patches are for good measure, since I was already touching
the code there.
When doing this, I discovered sound/soc/codecs/rt1016.c is not in a
Makefile, so there is not really any way to build it (I added locally to
the Makefile to compile-test my changes). Is this expected or an oversight?

Skylake is dependent on SND_SOC_INTEL_SKYLAKE (aka "all SST platforms")
whereas selecting specific configuration such as KBL-only will not
cause driver code to compile. Switch to SND_SOC_INTEL_SKYLAKE_COMMON

snd_soc_dai_set_drvdata is not needed when the set data comes from
snd_soc_dai_get_drvdata or dev_get_drvdata. The problem was fixed
usingthe following semantic patch: (http://coccinelle.lip6.fr/)
