Description of the changes
When running ACE on the SiFive P550 evaluation board, we recognized performance degradation due to inefficient trap handler implementation. Specifically, for interrupt in the system, we were making unnecessary memory store before handling the call to OpenSBI. This PR shortens the path, redirecting the execution to OpenSBI as soon as possible.
