[SCSI] mpt3sas: add new driver supporting 12GB SAS
These driver files are initially, substantially similar to mpt2sas but, because mpt2sas is going into maintenance mode and mp3sas will become heavily developed, we elected to keep the code bases separate.

19 * Date Version Description
20 * -------- -------- ------------------------------------------------------
21 * 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
22 * 10-31-07 02.00.01 Fixed name for pMpi2SCSITaskManagementRequest_t.
23 * 12-18-07 02.00.02 Modified Task Management Target Reset Method defines.
24 * 02-29-08 02.00.03 Added Query Task Set and Query Unit Attention.
25 * 03-03-08 02.00.04 Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
26 * 05-21-08 02.00.05 Fixed typo in name of Mpi2SepRequest_t.
27 * 10-02-08 02.00.06 Removed Untagged and No Disconnect values from SCSI IO
28 * Control field Task Attribute flags.
29 * Moved LUN field defines to mpi2.h becasue they are
30 * common to many structures.
31 * 05-06-09 02.00.07 Changed task management type of Query Unit Attention to
32 * Query Asynchronous Event.
33 * Defined two new bits in the SlotStatus field of the SCSI
34 * Enclosure Processor Request and Reply.
35 * 10-28-09 02.00.08 Added defines for decoding the ResponseInfo bytes for
36 * both SCSI IO Error Reply and SCSI Task Management Reply.
37 * Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
38 * Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
39 * 02-10-10 02.00.09 Removed unused structure that had "#if 0" around it.
40 * 05-12-10 02.00.10 Added optional vendor-unique region to SCSI IO Request.
41 * 11-10-10 02.00.11 Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
42 * 11-18-11 02.00.12 Incorporating additions for MPI v2.5.
43 * 02-06-12 02.00.13 Added alternate defines for Task Priority / Command
44 * Priority to match SAM-4.
45 * Added EEDPErrorOffset to MPI2_SCSI_IO_REPLY.
46 * 07-10-12 02.00.14 Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.
