[PATCH 01/10] mpt3sas: Processing of Cable Exception events

[Sreekanth Reddy <sreekanth.reddy@broadcom.com>]

Earlier Active Cable Exception event with reason code
"Cable Degraded (0x02))" was added only for Active Cable,
Now this event is extended to Passive cable too.
So re-arranged display message accordingly.

Also added Cable Exception Event even for SAS3008 & SAS3108 HBAs
(i.e. MPI 2.5 spec supporting HBAs) earlier this event was
enabled only for MPI 2.6 spec supporting HBA devices.
