ASoC: Intel: bytcr_rt5640: Add quirk for the Advantech MICA-071 tablet



[ Upstream commit a1dec9d70b6ad97087b60b81d2492134a84208c6 ]

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.
