[alsa-devel] [PATCH 2/2] ASoC: Intel: byt-rt5640: Enable DMIC interface for default DAPM route

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.
