staging:iio: Differential channel handling - use explicit flag rather than types.
Straight forward change in the core, but required some drivers to not use
the IIO_CHAN macro as that doesn't allow setting this bit (and is
going away anyway). Hence the churn.
Tested on max1363 with a couple of supported parts.
V2: differential bit in code got 7 bits and direction 1. Reversed that.
Issue spotted by Michael - thanks!
