It turned out DMIC interface wasn't enabled/disabled runtime for active DMIC route in the rt5640 codec driver anymore after commit 71d97a794301 ("ASoC: rt5640: Use the platform data for DMIC settings").
Since DMIC interface must be enabled explicitly either by passing platform data to rt5640 codec driver or by calling new rt5640_dmic_enable() this patch adds a DMI quirk flag that is used to conditionally enable DMIC interface during sound card init time.
