[PATCH] iio/adc: depend on SYSFS instead of selecting it

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

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.
