ASoC: wm8996: Put the microphone biases into bypass mode when idle
When we're not actively doing audio we don't need the microphone biases to be regulated, noise is not important when we are not looking at the audio signal. Save some power by putting the MICBIAS regulators into bypass mode when not doing audio. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
