The Resource Power Manager (RPM) currently does not have a dedicated
device tree node that represents the remoteproc/subsystem. The
functionality exposed through the SMD/GLINK channels is described in
top-level nodes of the device tree. This makes it hard to group other
functionality provided by the RPM together in the device tree. This
series adds a single top-level remoteproc-rpm/rpm-proc device tree node
that groups all RPM functionality together.

Changes in v2:
- Pick up review/test tags from Konrad and Krzysztof
- Rename "remoteproc-rpm" -> "remoteproc" everywhere (Krzysztof/Konrad)
- "dt-bindings: remoteproc: Add Qualcomm RPM processor/subsystem"
- Squash with other dt-bindings changes to have atomic refactoring (Krzysztof)
- Add diagrams from discussion as clarification
- "soc: qcom: smem: Add qcom_smem_is_available()"
- Add return documentation in qcom_smem_is_available() (Konrad)
- "soc: qcom: Add RPM processor/subsystem driver"
- Add missing of_node_put(), fix children (Konrad)
- Add depends on RPMSG_QCOM_SMD || RPMSG_QCOM_SMD=n to fix build
error in weird kernel configurations (kernel test robot)
