Subject: [PATCH 02/11] staging: iio: adt7316: invert the logic of the check for an ldac pin

ADT7316_DA_EN_VIA_DAC_LDCA is set when the dac and ldac registers are being
used to update the dacs instead of the ldac pin. ADT7516_SEL_AIN3 is an adc
input that shares the ldac pin. Only set these bits if an ldac pin is not
being used.
