ASoC: mediatek: mt8195: extract SOF common code

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.
