scsi: elx: libefc_sli: SLI-4 register offsets and field definitions
This is the initial patch for the new Emulex target mode SCSI driver. - Create the new Emulex source level directory drivers/scsi/elx and add the directory to the MAINTAINERS file. - Create the first library subdirectory drivers/scsi/elx/libefc_sli. This library is a SLI-4 interface library. - Start the population of the libefc_sli library with definitions of SLI-4 hardware register offsets and definitions.
