This function is used to register/un-register event notification with XilSEM Server. Primarily this function sends an IPI request to PLM to invoke SEM Event Notifier registration, waits for PLM to process the request and check the status. Since SLR slave devices do not support IPI, registering events to mater registers events on all slave SLRs.

Note: The caller shall initialize the notifier object before invoking the XSem_RegisterEvent function.
