3.19.8-ckt10 -stable review patch. If anyone has any objections, please let me know.

commit dd6ae3bcfe0fa9cf1bdb6f952c617f2070c57b37 upstream.
The last parameter for DECLARE_TLV_DB_SCALE() is to tell if the gain will be muted or not when it is set to raw 0. IN this case it is not muted. The PGA_GAIN is in 0-4 bits in the register. Fix the offset in the SOC_SINGLE_TLV() for this.
