Rather than using kernel version checks to determine which kernel APIs
to use, add the necessary tests to the conftest script to determine
which kernel APIs are present in the kernel.
Note that the function snd_soc_dai_init_dma_data() has been present
in the Linux kernel since v3.13 and so use this for all kernel versions.
In Linux v6.3, the 'playback_dma_data' and 'capture_dma_data' members of
the snd_soc_dai_driver structure were replaced and so these could no
longer be set directly. However, the arguments to
snd_soc_dai_init_dma_data() have not changed and so can be used for
older kernels and well has the current.
This is beneficial for working with 3rd party Linux kernels that may
have back-ported upstream changes into their kernel and so the kernel
version checks do not work.

In Linux v6.4, the 'params' member of the snd_soc_dai_link was replaced
with the 'c2c_params' member. Add a new test to the conftest script that
checks if the 'c2c_params' structure member is present and use the
definition created by conftest to select which structure member is used.

It is nice to have downstream DTB working well with upstream kernel
drivers. This gives a flexibile option for users to choose between
out-of-tree and upstream audio drivers by selectively adding either
of these to deny list.
For clock PLLA_OUT0, upstream DT uses 'plla_out0' clock name where
as downstream uses 'pll_a_out0'. So aligning with upstream DT makes
probe to fail. Thus update the clock name in driver to match upstream
DT bindings.
The sound DT supports compatibles to either work with upstream or
downstream machine drivers. Earlier the source 'tegra_codecs.c' was
modified to make it potentially usable for upstream machine driver
as well and thus it has upstream compatible checks. This check is
now replaced with a flag which is known to be set only during
upstream machine driver probe.

Upstream Linux kernel commit 3989ade2d1e7 ("ASoC: soc.h: remove
num_cpus/codecs") removes the 'num_cpus' member from the
'snd_soc_pcm_runtime' structure because this is also available under the
dai_link structure. This breaks building the Tegra ASoC drivers for
Linux v6.1 and so update the Tegra ASoC drivers to align the latest
mainline.

Build errors seen in following contexts with kstable:
- The 'non_legacy_dai_naming' flag is not available in struct
'snd_soc_component_driver' in v6.0. Instead it is replaced
with flag 'legacy_dai_naming' and default value works fine.
To fix build error on kstable exclude the removed flag for
kernel v6.0 onward.
- Signature of snd_soc_card_jack_new() has changed in v5.19
which drops struct 'snd_soc_jack_pins' related members. These
were unused for Tegra and is safe to just update the funcion
call. Fix this by using correct function signature based on
kernel version checks.
With above fixed now, remove workaround from Makefile and enable
Audio OOT driver builds again with kstable.

This is a standard policy adopted by kernel distributors and to

Due to a shortage of RT5658 codec parts, search was going on for an
alternative codec. As a replacement, RT5640 codec is finalized now.
The upcoming Concord boards (EB3 to begin with) will have this codec.
This commit adds required support in the machine driver.
Machine driver update is needed for following reasons:
* The RT5640 codec driver expects sysclk configuration from machine
driver. This requirement is similar to what we have today for
RT5658 codec. This handling is done under "rt5640-playback" DAI
link name.
* RT5640 DAI link init is added for jack setup. Since it is mostly
similar to RT5658 handling, the existing init helper function is
re-used. The component driver jack setup callback is used to make
this simple.

Tegra platforms support multiple external codecs which in some cases
require initial setup or runtime setup. Since common machine driver is
used, it uses DAI link names passed from DT to apply specific settings.
Use the same logic for Tegra audio graph card driver as well. In doing
so separate out codec setup part and move the same to tegra_codec.c
source file. This is reference in current downstream machine driver
and future Tegra audio graph card driver.
Going ahead alternate solution need to be identified to avoid dependency
on DAI link names. Upstream generic audio graph driver does not support
such method and passing DAI link names from DT won't be entertained in
upstream.
