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 Change-Id: Ic46d4c7b30b945eba47a05d78386f48e4a675a03 Signed-off-by: Sathyanarayana Nujella <sathyanarayana.nujella@intel.com> Reviewed-on: https://review.coreboot.org/19018 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Venkateswarlu V Vinjamuri <venkateswarlu.v.vinjamuri@intel.com> Tested-by: build bot (Jenkins)
