[SCSI] mptfusion: Support SAS2.0 Devices with SAS1.0 Controllers
SAS1.0 Controller was not able to detect SAS2.0 Expanders due to Link RATE detection was limited to 1.5 Gbps and 3.0 Gbps for SAS1 controllers. Added detection for 6.0 Gbps link. Now, user can mix-up 6.0 Gpbs links with SAS1.0 controller. e.g SAS1.0 HBA <----> SAS2.0 Expander <------> SAS2.0 Expander <--------> SAS1.0 Drive.
