ENGR00253290-1 ASoC: wm8962: fix over-gained audio playback issue
We put some code to set default volumes in codec driver, but later we found that one of volume was higher than 0db, which would cause over-gained volume. So this patch removed DAC default volume setting, and reverted the volume interface of it to let user control the register from user space.
