Apart from a dai_link_list variable, the mtk_sof_priv currently holds data that never gets modified during runtime. Constify the mtk_sof_priv structure and move the SOF dai_link_list as sof_dai_link_list in struct mtk_soc_card_data, which is a structure that already holds the card's machine specific, runtime modified data. This allows to safely pass the mtk_sof_priv structure as platform data for the commonized card probe mechanism.
