Rework the regulator constraints for the MSM8916 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.
To make the regulator constraints more easily maintainable with a large
number of similar MSM8916 boards I propose moving the voltages for the
standard components in the SoC to the shared msm8916-pm8916.dtsi
include. With this only the actual board-specific regulators are
described in the board DT.
