Run platform-specific secure functions in default secure partition, in which SYS/CLK spaces have been configured to be accessible.	2020-01-06 15:55:00 +08:00

[M2351] Enforce locked entry into TFM for platform-specific NSC calls

On M2351, some spaces like SYS/CLK are hard-wired to secure and cannot change.
To access these spaces from non-secure world, we must provide platform-specific NSC
functions. With TFM introduced, we must synchronize NSC calls into TFM to keep TFM
in sync instead of straight NSC calls. To achieve this goal, we go with the following
approach:

1. Like PSA APIs, enforce locked entry through tfm_ns_lock_dispatch().
2. Run platform-specific secure functions in default secure partition, in which SYS/CLK
   spaces have been configured to be accessible.
