Board designs (and accompanying device trees) may not provide exactly the voltage listed here, and we shouldn't fail to probe just because of this. Round these ranges down to the nearest volt, and provide a 0.05V margin. The regulator should provide its own supported ranges, which will helpfully intersect with these ranges. I would just as well remove these ranges entirely, but if I understand correctly, there's some reason that QCOM SoC's like to set zero / non-zero voltages.
