The correct ranges can be seen in the "native" spmi regulator driver qcom_spmi-regulator.c at pldo_ranges[], ftsmps_ranges[] and boost_ranges[] for the pldo, ftsmps, and boost type regulators. Port these ranges over to the RPM SMD regulator driver so that we list the appropriate set of supported voltages on pldos. Doing this allows us to specify a voltage like 3075000 for l24, whereas before that wasn't a supported voltage.
