scsi: mpt3sas: Reload SBR without rebooting HBA
Add a new IOCTL command MPT3ENABLEDIAGSBRRELOAD. As a part of firmware
update operation, applications use this IOCTL command to set the SBR reload
bit in the Host Diagnostic register. This permits HBA firmware to be
updated without powercycling the system.
