[PATCH 4/6] dt-bindings: soc: qcom: convert non-smd RPM bindings to dt-schema

[Neil Armstrong <neil.armstrong@xxxxxxxxxx>]

Convert the non-SMD RPM node bindings to dt-schema, the regulators subnode
refers to regulators,yaml until we have the proper bindings.

+title: Qualcomm Resource Power Manager (RPM) over IPC
+
+description: |
+  This driver is used to interface with the Resource Power Manager (RPM) found
+  in various Qualcomm platforms. The RPM allows each component in the system
+  to vote for state of the system resources, such as clocks, regulators and bus
+  frequencies.
