iio: mxs-lradc: add scale attribute to channels
Some LRADC channels have fixed pre-dividers and all have an optional
divider by two which allows a maximum input voltage of VDDIO - 50mV.
This patch
- adds the scaling info flag to all channels
- grabs the max reference voltage per channel
(where the fixed pre-dividers apply)
- allows to read the scaling attribute (computed from the Vref)
