BUG: Need to understand what a Realm Instance refer to?

[yogeshbdeshpande]

The meaning and interpretation of Realm Instance is very much dependent on the use case and deployment.

For some use cases, where every Realm is uniquely programmed, Realm Instance could be Real Initial Measurements (RIM).

For some cases, where the host want to instantiate same Workload for concurrency it can use N Realms with same RIM. Then Realm Instance could be a RIM+RPV.

Need to clearly identify use cases and come up with a coherent Realm Instance narrative for Arm CCA.
