Subject: [PATCH] firmware: arm_sdei: pass sdei_api_event_register right parameters

Function _local_event_enable is used for private sdei event
registeration called by sdei_event_register. We should pass
sdei_api_event_register right flag and mpidr parameters, otherwise atf
may trigger assert errors.
