Sergiu Cuciurean 9d708a3b72 iio: adc: ad7768-1: Fix conversion result sign
[ Upstream commit 8236644f5e ]

The ad7768-1 ADC output code is two's complement, meaning that the voltage
conversion result is a signed value.. Since the value is a 24 bit one,
stored in a 32 bit variable, the sign should be extended in order to get
the correct representation.

Also the channel description has been updated to signed representation,
to match the ADC specifications.
