ASoC: tegra: Fix build for Linux v6.4

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.
