[PATCH v2 00/10] riscv: add initial RPMI virt support

[Subrahmanya Lingappa <subrahmanya.lingappa@oss.qualcomm.com>]

Add optional librpmi support and the initial RISC-V virt RPMI
implementation. This series introduces the shared-memory transport, FDT
helpers, opt-in virt wiring, and the Base, System Reset, HSM, and System
Suspend service groups with qtest and functional coverage.

The implementation targets the RISC-V Platform Management Interface
(RPMI) Specification v1.0 Ratified and uses librpmi as the backend.

Changes since v1:
