Add device tree bindings for the RISC-V Platform Management Interface (RPMI) device power service group, both for the supervisor-facing power domain controller and for the SBI MPXY channel which the SBI implementation uses to expose the service group.

Add a generic power domain provider on top of the RISC-V Platform Management Interface (RPMI) device power service group, reached through an SBI MPXY channel. The driver enumerates the device power domains advertised by the platform microcontroller, queries their attributes and initial state, and registers them as an onecell genpd provider so that devices can reference them through the "power-domains" property.

Add a separate entry for the RPMI device power driver and its bindings, rather than extending the existing RISC-V RPMI and MPXY drivers entry, which covers drivers maintained by others.
