The functions related to SOF can be reused in different machine drivers, such as mt8195 or mt8186, so extract the common code to avoid duplication.

Set mtk_soc_card_data which include machine private data and SOF private data as card drvdata, then the difference between machine private can be ignored such as mt8195_mt6359_priv or mt8186_mt6366_priv, at the same time the SOF related code can be reused in different machine drivers.
