[PATCH 04/10] arm64: dts: qcom: msm8916: Add RPM power domains

MSM8916 has two RPM power domains: VDDCX and VDDMX.
So far we have been managing them by voting for raw voltages through
the regulator subsystem, but it's better to manage them with corners
as actual power domains.

Add the device tree node for rpmpd so we can manage them as real
power domains instead of using the regulators.
