Arm SCMI updates for v7.0

A set of cleanups, refactoring, and fixes to the Arm SCMI stack:

1. Rework protocol version negotiation by moving version discovery and
   downgrade handling into the SCMI core and performing negotiation early,
   before protocol initialization. Remove legacy per-protocol versioning
   logic now made redundant by centralized SCMI handling.

2. Increase the internal MAX_OPPS limit in the SCMI performance protocol
   to 64, allowing platforms with larger OPP tables to be fully supported.

3. Reduce duplicated boilerplate in pinctrl and related protocols by
   consolidating validation and lookup logic in protocol get info helpers.

4. Refactor reset protocol domain handling by introducing a shared lookup
   helper, ensuring consistent validation and error reporting.

5. Fix potential undefined behaviour by properly initializing pointers
   annotated with the __free attribute.
