ASoC: Intel: bytcr_rt5640: Add quirk for the Advantech MICA-071 tablet
The Advantech MICA-071 tablet deviates from the defaults for
a non CR Bay Trail based tablet in several ways:
1. It uses an analog MIC on IN3 rather then using DMIC1
2. It only has 1 speaker
3. It needs the OVCD current threshold to be set to 1500uA instead of
the default 2000uA to reliable differentiate between headphones vs
headsets
Add a quirk with these settings for this tablet.
