scsi: lpfc: Add support for 32 byte CDBs
The driver's I/O path is updated to support 32 byte CDBs.
Changes to accommodate 32 byte CDBs include:
- Updating various size fields to allow for the larger 32 byte CDB.
- Starting the FCP command payload at an earlier offset in WQE submission
to fit the 32 byte CDB.
- Redefining relevant structs to __le32/__be32 data types for proper cpu
endianness macro usage.
