This series fixes the following mixer control related issues:
- "Headphone Volume" and "PGA Volume" have been reset after previous
  stream closed.
- Set "Headphone Volume" to the smallest value (-10dB) still get mute,
  because ramp from -10dB to -10dB is a NOP in original implementation.

"Lineout Volume" and "Handset Volume" are un-tested.  Fixing them by
applying similar logic with "Headphone Volume".

Tzung-Bi Shih (3):
  ASoC: mediatek: mt6358: initialize setting when ramping volume
  ASoC: mediatek: mt6358: save output volume for mixer controls
  ASoC: mediatek: mt6358: save PGA for mixer control
