iio: health/afe440x: Make gain settings a modifier for the stages
Currently the TIA gain settings are exported to userspace as sysfs entries that do not clearly represent their internal relation to the sampling stages. The gain settings are enabled on a per-stage basis, this can be seen in figure 24 of the current AFE4404 datasheet. These gain settings should therefore be tied to the channels that are read during these stages. Make this change here. Signed-off-by: Andrew F.
