Angelo Dureghello f083f8a21c iio: adc: ad7606: fix serial register access 
Fix register read/write routine as per datasheet.

When reading multiple consecutive registers, only the first one is read
properly. This is due to missing chip select deassert and assert again
between first and second 16bit transfer, as shown in the datasheet
AD7606C-16, rev 0, figure 110.

Fixes: f2a22e1e17 ("iio: adc: ad7606: Add support for software mode for ad7616")
