Partially reverts commit 128f825a ("ASoC: max98357a: move control of SD_MODE to DAPM"). In order to have mute control of max98357 from machine drivers, commit 128f825a ("ASoC: max98357a: move control of SD_MODE to DAPM") moves the control of SD_MODE from DAI ops to DAPM events. However, pop noise has been observed on rk3399-gru-kevin boards due to this commit. The commit 128f825a caused sequence of DAI clocks and SD_MODE changed on rk3399-gru-kevin boards. With the commit 128f825a: - SD_MODE will be set to 1 before DAI clocks start. - SD_MODE will be set to 0 after DAI clocks stop. As a result, pop noise. Moves the control of SD_MODE back to DAI ops. In the meantime, uses an additional flag in DAPM event to provide chance of mute control for machine drivers.
