From: "Shane.Chien" <shane.chien@mediatek.com>

This series of patches is to fix vaud18 power leakage problem.
vaud18 will be enable only when mt6359 audio path is turned on.

Change since v2:
 - fix dt-binnding syntex error

Change since v1:
 - use dapm regulator supply widget for vaud18 control.
 - add vaud18 regulator property in mt6359 dt-binding.

  ASoC: Fix vaud18 power leakage of mt6359
  dt-bindings: mediatek: mt6359: Add new property for mt6359
