mb/google/reef: Correct channel count for DMIC

These boards only have 2 DMIC physically connected, and attempting to
record from 4 channels vs 2 results in a large amount of background
noise which drowns out the recording. Selecting the 2 channel DMIC
shows audio on both channels and no noise.

TEST=build/boot reef variants, test built-in mic under Windows
and Linux.
