[PATCH 6/6] ASoC: nau8822: Fix the 128x oversampling switch bits

[HyeongJun An]

The DAC and ADC 128x Oversampling Switches use bit 5 of R10 and R14.
The NAU8822 datasheet register map puts DACOS and ADCOS at bit 3 of
those registers.

In R14, bit 5 is inside HPF[6:4], which the High Pass Cut Off control
owns. So turning on ADC oversampling changes the high pass cut-off, and
the oversampling bit cannot be set. In R10, bit 5 is reserved, so the
DAC switch has no effect.

Use bit 3 for both.
