mpt3sas: Ported WarpDrive product SSS6200 support
Ported the following list of WarpDrive-specific patches:
1. commit 0bdccdb0a090ad8dc5f851cad5e843244c410ee8 ("mpt2sas: WarpDrive
New product SSS6200 support added")
2. commit 82a452581230b3ffc9d6475dffdb2568497b5fec ("mpt2sas: WarpDrive
Infinite command retries due to wrong scsi command entry in MPI
message")
3. commit ba96bd0b1d4a4e11f23671e1f375a5c8f46b0fe7 ("mpt2sas: Support
for greater than 2TB capacity WarpDrive")
4. commit 4da7af9494b2f98a1503a2634059300c3e4615e6 ("mpt2sas: Do not
retry a timed out direct IO for Warpdrive")
5. commit daeaa9df92bd742f4e6d4d6039d689277a8e31bd ("mpt2sas: Avoid type
casting for direct I/O commands").
Also set the mpt2_ioctl_iocinfo adapter_type to:
1. MPT3_IOCTL_INTERFACE_SAS3 for Gen3 HBAs
2. MPT2_IOCTL_INTERFACE_SAS2_SSS6200 for Warp Drive
3. MPT2_IOCTL_INTERFACE_SAS2 for other Gen2 HBAs
