[SCSI] mpt2sas : Identify Dell series-7 adapters at driver load time

The Dell branding along with the VID, DID, SSVID, SSDID following the LSI
branding that contains the card firmware/chip/bios versions.  If the SSDID
is not known but it is a Dell HBA, the driver will print the SSDID instead
of the Dell branding string.  Nothing will be printed for non Dell HBAs
