Commit b4fe47d1 ("arm64: dts: qcom: qrb2210-rb1: Add regulators")
introduced regulator settings that were never put in place, as all of the
properties ended 'microvolts' instead of 'microvolt' (which dt schema did
not check for back then).

Fix the microvolts-microvolt typo and adjust voltage ranges where it's
necessary to fit within the volt = base + n*step formula.
