ASoC: codecs: ES8326: Add es8326_mute function

Browse source

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.
