[PATCH AUTOSEL 6.2 07/20] ASoC: Intel: bytcr_rt5640: Add quirk for the Acer Iconia One 7 B1-750

[ Upstream commit e38c5e80c3d293a883c6f1d553f2146ec0bda35e ]

The Acer Iconia One 7 B1-750 tablet mostly works fine with the defaults
for an Bay Trail CR tablet. Except for the internal mic, instead of
an analog mic on IN3 a digital mic on DMIC1 is uses.

Add a quirk with these settings for this tablet.
