Firmware can report various MPI Events.
Support for certain Events (as listed below) are enabled in the driver
and their processing in driver is covered in this patch.
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
Key support in this patch is device add/removal.
Fix some compilation warning reported by kernel test robot.
