The driver is using the set_bias_level to control the power on and off so it should get SND_SOC_BIAS_OFF in order to proceed normal powering sequences. This patch enables the idle_bias_off option so the DAPM core will set the bias level to SND_SOC_BIAS_OFF instead of stopping at SND_SOC_BIAS_STANDBY.
