Sameer Pujar 47b127bd17 ASoC: tegra: Fix build errors with kstable 
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.

Bug 3831575
