ASoC: twl6040: Workaround for headset DC offset caused pop noise
Both Headset DAC need to be turned on/off at the same time before any of the output drivers are enabled (HS Left/Right, Earpiece). Move the HS DAC enable code to sequenced DAPM_SUPPLY, and attach it to the DACs. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
