Modified the mpt3sas driver to have a single driver module which
support both SAS 2.0 & SAS 3.0 HBA devices,
Change List:
* Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table.
* Created two separate SCSI host templates for SAS2 and SAS3 HBAs.
so that, during the driver load time driver can use
corresponding host template(based the pci device ID) while
registering a scsi host adapter instance for that pci device.
* Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl
for SAS3 HBAs. Also updated the code to make sure that mpt2ctl
device to process only those ioctl cmds issued for the SAS2 HBAs
and mpt3ctl device to process only those ioctl cmds issued for
the SAS3 HBAs.
* Added two separate indexing for SAS2 and SAS3 HBAs.
* Replaced compile time check 'MPT2SAS_SCSI' to run time check
'hba_mpi_version_belonged' whereever needed.
* Aliased this merged driver to mpt2sas using MODULE_ALIAS.
* Moved global varaible 'driver_name' to per adapter instance variable.
* Created two raid function template and used corresponding
raid function templates based on the run time check
'hba_mpi_version_belonged'.

+ This option allows you to specify the maximum number of scatter-
