edba59f3cd 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.
