iio/adc: depend on SYSFS instead of selecting it
Drivers should not 'select' a subsystem. Instead they should depend on it. If the subsystem is disabled, the user probably did that for a purpose and one driver shouldn't be changing that. This also makes all IIO drivers consistent w.r.t depending on SYSFS instead of selecting it.
