[PATCH v8 00/10] riscv: add initial RPMI virt support

This series adds initial librpmi-backed RPMI support for the RISC-V virt
machine. It covers the optional librpmi build dependency, the RPMI
transport and Base service, virt FDT wiring, opt-in machine support,
System Reset, HSM, System Suspend, documentation, qtests and a Linux
guest smoke test.

Changes since v7:
- Drop the redundant internal RiscvRpmiServiceKind field from
  RiscvRpmiServiceConfig and use service_group as the single dispatch and
  FDT service identifier.
- Move the RiscvRpmiServiceOps table and service_group lookup
  infrastructure into the System Reset patch, so the HSM and System
  Suspend patches only add their own service entries.

Changes since v6:
- When RPMI is enabled, advertise reboot and shutdown through the RPMI
  system reset service instead of the syscon reset nodes.
- Extend the functional guest smoke test to check the RPMI reboot and
  shutdown devices reported by firmware and exercise the reboot path.
