ASoC: mediatek: add MTK_PMIC_WRAP dependency

Randconfig builds often show harmless warnings like

WARNING: unmet direct dependencies detected for SND_SOC_MT6359
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && MTK_PMIC_WRAP [=n]
  Selected by [y]:
  - SND_SOC_MT8192_MT6359_RT1015_RT5682 [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && I2C [=y] && SND_SOC_MT8192 [=y]

Add a dependency to avoid that.
