iio: ad_sigma_delta: select channel when reading register
The desired channel has to be selected in order to correctly fill the
buffer with the corresponding data.
The `ad_sd_write_reg()` already does this, but for the
`ad_sd_read_reg_raw()` this was omitted.
Fixes: af3008485ea03 ("iio:adc: Add common code for ADI Sigma Delta devices")
