ASoC: max98357a: move control of SD_MODE back to DAI ops
Partially reverts commit 128f825aeab7 ("ASoC: max98357a: move control
of SD_MODE to DAPM").
In order to have mute control of max98357 from machine drivers, commit
128f825aeab7 ("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 128f825aeab7 caused sequence of DAI clocks and SD_MODE
changed on rk3399-gru-kevin boards.
With the commit 128f825aeab7:
- 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.
