dt-bindings: power: Add rpmh power-domain bindings for SM8150

	* qcom,msm8998-rpmpd: RPM Power domain for the msm8998 family of SoC

	* qcom,qcs404-rpmpd: RPM Power domain for the qcs404 family of SoC

	* qcom,sdm845-rpmhpd: RPMh Power domain for the sdm845 family of SoC

	* qcom,sm8150-rpmhpd: RPMh Power domain for the sm8150 family of SoC

 - #power-domain-cells: number of cells in Power domain specifier

	must be 1.

 - operating-points-v2: Phandle to the OPP table for the Power domain.
