dt-bindings: power: Add qcom rpm power domain driver bindings

Browse Source 
Add DT bindings to describe the rpm/rpmh power domains found on Qualcomm
Technologies, Inc. SoCs. These power domains communicate a performance
state to RPM/RPMh, which then translates it into corresponding voltage on a
PMIC rail.
