scsi: mpi3mr: Add support for device add/remove event handling
Firmware can report various MPI Events. Enable support for processing the
following events related to device addition/removal to the driver:
- MPI3_EVENT_DEVICE_ADDED
- MPI3_EVENT_DEVICE_INFO_CHANGED
- MPI3_EVENT_DEVICE_STATUS_CHANGE
- MPI3_EVENT_ENCL_DEVICE_STATUS_CHANGE
- MPI3_EVENT_SAS_TOPOLOGY_CHANGE_LIST
- MPI3_EVENT_SAS_DISCOVERY
- MPI3_EVENT_SAS_DEVICE_DISCOVERY_ERROR
