staging:iio:ad7192: Mark channels as unsigned

The values reported by the AD7793 are unsigned.
In uniploar mode:
0x000000 is zeroscale
0xffffff is fullscale
In bipolar mode:
0x000000 is negative fullscale
0x800000 is zeroscale
0xffffff is positive fullscale

In bipolar mode there is a binary offset, but the values are still unsigned.
