Rework the regulator constraints for the MSM8939 device trees to be closer to reality. There are several mistakes in there, some of them taken over directly from Qualcomm's vendor kernel. Fortunately, none of the mistakes is absolutely critical because it turns out that the RPM firmware also validates the voltages and silently clamps the requests to a proper range. Still, this behavior should be clearly represented in the device tree rather than pretending to apply the wrong voltages. Apply the same changes as previously for MSM8916 [1] and move the voltages for the standard components in the SoC to the shared msm8916-pm8939.dtsi. With this only the actual board-specific regulators are described in the board DT.
