Lars-Peter Clausen 70e01880a9 staging:iio:ad7780: Mark channels as unsigned
The values reported by the AD7780 are unsigned with a binary offset:

	0x000000 is negative fullscale
	0x800000 is zeroscale
	0xffffff is positive fullscale

So mark the channel in the channel spec as unsigned rather than signed.
