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.

Starting with Linux kernel v5.17, the 'slave_id' member is removed from
the DMA Engine 'dma_slave_config' structure. Building the Tegra Safety
Audio driver against Linux v5.17, v5.18 and v5.19 breaks because this
filed is not defined. There are already comments in the driver to not
used the 'slave_id' field and move to using device-tree to get this
information. For now, fix the build by not using the 'slave_id' field
for Linux v5.17+.
