The internal analog power and hp Vref of es8326 should always be on to reduce pop noise. The HP_VOL and HP_CAL are moved to es8326_mute function so they are turned on at last and turned off at first.
Also, the calibration should be done manually once during start-up to reduce DC offset on headphone.
