ENGR00230381 There is noise for some bitstream
Revert "ENGR00219882 wm8962: avoid the digital volume changed by user"
This reverts commit 18079ec20d80ecccf8279c70c9e67b6ebf8b3f22.
Digital volume will be used by the DSP of wm8962 to scale the input digital
signal. Main branch remove this mixer control, but set the default value
exceed 0dB, which will cause noise when the signal has maximum amplitude.
Move this control back, then the user space can set this value by itself.
