This function is used to start NPI scan from user application. Primarily this function sends an IPI request to PLM to invoke SEM NPI StartScan, waits for PLM to process the request and reads the response message. In case of EL1 Non-Secure mode, this function generates an SMC call to TF-A. The SMC request goes to the PLM through the TF-A. This function reads the response of the SMC call and returns the status.
