Remove IPGA volume controls and merge the IPGA range to ADC volume controls. These two volumes are not really independent but connected simply in different ranges 0-0x7f and 0x80-max. It doesn't make sense to provide two controls. Since both 0x7f and 0x80 specify 0dB, a hack is needed for IPGA range to skip 0x80 (increment one) for such controls.
