ASoC: es8328: Fix ADC format setup
The ADCCONTROL4 and DACCONTROL1 registers are similar but not identical, with the DACCONTROL1 having each field starting one bit higher than ADCCONTROL4. Instead of introducing a magic shift, add new constants for the values in ADCCONTROL4 and use a second variable to setup the ADC.
