scsi: mpi3mr: Support Prepare for Reset event

Browse source

The IOC sends a Prepare for Reset Event to the host to prepare for a Soft
Reset. This event data has two reason codes:

 1. Start - The host is expected to gracefully quiesce all I/O within
    approximately 1 second.

 2. Abort - The IOC is requesting to abort a previous Prepare for Reset
    Event request. Normal I/O may be resumed.
