Arm SCMI updates/fixes for v6.18

These SCMI changes bring a mix of improvements, fixes, and cleanups:

1. Device Tree bindings - allow multiple SCMI instances by suffixing
   node names (Nikunj Kela).
2. Code hardening - constify both scmi_{transport,voltage_proto}_ops
   so they reside in read-only memory (Christophe JAILLET).
3. VirtIO transport initialization - set DRIVER_OK before SCMI probing
   to prevent potential stalls; while recent rework removes the practical
   risk, this ensures correctness (Junnan Wu).
4. Quirk handling - fix a critical bug by preventing writes to string
   constants, avoiding faults in read-only memory (Johan Hovold).
5. i.MX SCMI MISC protocol - extend support to discover board info,
   retrieve configuration and build data, and document the new
   MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan).
6. Logging cleanup - simplify device tree node name logging by using
   the %pOF format to print full paths (Krzysztof Kozlowski).
