hda_dai_hw_params, hda_dai_trigger(), hda_dai_hw_free are currently only used for HDaudio codec support, but will be reused for SSP/DMIC/SoundWire in the LunarLake/ACE2.x case. To avoid 'defined but not used' errors or added complexity in Kconfig, mark all these functions as __maybe_used.
When SSP/DMIC/SoundWire are added, some of these changes may be reverted. For now this avoids compilation warnings.
