ASoC: pcm3168a: Fix the DAC zero flag polarity bit
The DAC Zero Flag Polarity enum uses PCM3168A_DAC_ATSPDA_SHIFT, which
is bit 6 of register 70. That bit is ATSPDA, the attenuation speed,
which the DAC Volume Rate Multiplier enum already owns. The datasheet
puts ZREV, the zero flag polarity, at bit 0. The header defines
PCM3168A_DAC_ZREV_SHIFT for it, but nothing uses it.
So changing the zero flag polarity changes the attenuation speed, and
ZREV cannot be set.
Use PCM3168A_DAC_ZREV_SHIFT.
