ASoC: wm8978: Fix the 128x oversampling switch bits
The DAC and ADC 128x Oversampling Switches use bit 5 of R10 and R14.
Table 66 of the WM8978 datasheet puts DACOSR128 and ADCOSR128 at bit 3
of those registers.
In R14, bit 5 is inside HPFCUT[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.
