mpt3sas: Ported WarpDrive product SSS6200 support

Ported the following list of WarpDrive-specific patches:

1. commit 0bdccdb0 ("mpt2sas: WarpDrive
   New product SSS6200 support added")

2. commit 82a45258 ("mpt2sas: WarpDrive
   Infinite command retries due to wrong scsi command entry in MPI
   message")

3. commit ba96bd0b ("mpt2sas: Support
   for greater than 2TB capacity WarpDrive")

4. commit 4da7af94 ("mpt2sas: Do not
   retry a timed out direct IO for Warpdrive")

5. commit daeaa9df ("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
