lib: utils: Mark RPMI drivers as experimental

2024-12-21T12:52:47Z

These drivers were merged on an experimental basis without the RPMI specification being frozen. As a result, they may not be compatible with the frozen version of the RPMI protocol. Additionally, their devicetree bindings have not been reviewed and are subject to change. Warn the user that these drivers make no compatibility guarantees, and that their behavior and devicetree bindings may change incompatibly in future versions of OpenSBI.
