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

kernel that drivers are being compiled against. This is useful for cases
where changes are backported from upstream Linux kernels that may change
kernel functions and so we can no longer rely on the kernel version to

The conftest.h header file is a top-level header file that includes all
the header files that are generated by the conftest.sh script. This
header file can be included by drivers so that they can use the various
