staging: iio: cdc: ad7746: Switch from _offset to _zeropoint for differential channels.
As this offset is applied equally to both lines of the differential
pair, _ofset should not be used. Use the new ABI _zeropoint instead
to avoid userspace software applying this value when calculating
real value = (_raw + _offset) * _scale
Also add a comment to explain why an offset of 0x800000 is applied
within the driver rather than exposed to userspace.
