Why is this in DT rather than as a userspace control?

only currently defined for muxes but we have settle-time-us which has benefit of
providing the units (which are missing here from the description as well)

Why is this in dt? Why not just userspace control (in_voltageX_oversampling_ratio
If it needs to be, we do have standard DT bindings for it in adc.yaml
