iio: adc: ad7124: set initial ADC mode to idle

Browse source

During setup the st->adc_control is 0, which corresponds to a continuous
conversion mode. The reset value for channel 1 is to enable it. The
combined effect of these two is that the ADC will start conversions for
channel 1 without them being read.
This is not neccessarily a problem, but it is an unexpected behavior.

Set the ADC state to idle during setup to avoid this.
