[PATCH v5 08/18] ASoC: mediatek: mt8195: Migrate to the common mtk_soundcard_startup

[AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>]

Add a const mtk_pcm_constraints_data struct array with all of the
(again, constant) constraints for all of the supported usecases,
remove the duplicated functions and call mtk_soundcard_startup()
instead in all of the .startup() callbacks.
