staging:iio:ad7793: 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.
