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.
