scsi: mpt3sas: Add persistent Event trigger page 

Trigger Page2 is used to store information about Event triggers:

  31     24 23        16 15      8 7         0   Byte
 -----------------------------------------------
 |PageType  |PageNumber  |Reserved |PageVersion| 0x00
 -----------------------------------------------
 |Reserved  |ExtPageType |   ExtPageLength     | 0x04
 -----------------------------------------------
 |     Reserved          | NumMPIEventTriggers | 0x08
 -----------------------------------------------
 |                 MPIEventTriggerEntries      | 0x0C
 |                                             | 0xFC
 -----------------------------------------------

Number of MPI Event Trigger Entries currently stored in this page.  If this
is set to zero, there are no valid MPI-Event-Trigger entries available in
this page.

MPIEventTriggerEntry:

 - MPIEventCode [15:00]
   MPI Event code specified in MPI-Spec

 - MPIEventCodeSpecific [16:31]
   For Event Code “MPI2_EVENT_LOG_ENTRY_ADDED (0x0021)”,
   this field specifies the Log-Entry-Qualifier.
   For all other Event Codes, this field is reserved and not used

Maximum of 20-event trigger entries can be stored in this page.
