iio: admv1013: add mixer_vgate corner cases
Include the corner cases in the computation of the MIXER_VGATE register value. According to the datasheet: The MIXER_VGATE values follows the VCM such as, that for a 0V to 1.8V VCM, MIXER_VGATE = 23.89 VCM + 81, and for a > 1.8V to 2.6V VCM, MIXER_VGATE = 23.75 VCM + 1.25.
