regulator: add REGULATOR_LINEAR_VRANGE macro
REGULATOR_LINEAR_VRANGE is similar to REGULATOR_LINEAR_RANGE, but
allows a more natural declaration of a voltage range for a regulator,
in that it expects the minimum and maximum values as voltages rather
than as selectors.
Using voltages arguably makes this macro easier to use by drivers and
code using it can become easier to read compared to
REGULATOR_LINEAR_RANGE.
