0ea23660c7 ASoC: cs42l42: Wait at least 150us after writing SCLK_PRESENT 
There must be a delay of at least 150us after writing SCLK_PRESENT
before issuing another I2C write.

This is done using struct reg_sequence because it can specify a delay

snd_soc_dai_digital_mute() is internally using both
mute_stream() (1) or digital_mute() (2), but the difference between

		...
		else if (dai->driver->ops->mute_stream)
