Fix all smart charger values by having boards provide the RSENSE values
and perform the register calculations in the code.
The galp3-c, galp5, gaze16, and gaze17 do not seem to have the same
behavior as the rest of the boards, and further investigation is needed.
In the mean time, reduce their charge current values to preserve current
behavior.
