mainboard/google/reef: turn off DMIC_CLK_B1 in S0ix
Wake On Voice stream capture configuration is mono. It is sufficient
to keep DMIC_CLK_A1 on in S0ix; so, turning off DMIC_CLK_B1.
Power saving should be visible in the boards which has more
than one DMIC connected.
BUG=None
BRANCH=None
TEST=WoV and quad channel DMIC capture works
