[NEW] efct: Broadcom (Emulex) FC Target driver

This patch set is a request to incorporate the new Broadcom
(Emulex) FC target driver, efct, into the kernel source tree.

The driver source has been Announced a couple of times, the last
version on 12/18/2018. The driver has been hosted on gitlab for
review has had contributions from the community.
  gitlab (git@gitlab.com:jsmart/efct-Emulex_FC_Target.git)

The driver integrates into the source tree at the (new) drivers/scsi/elx
subdirectory.

The driver consists of the following components:
- A libefc_sli subdirectory: This subdirectory contains a library that
  encapsulates common definitions and routines for an Emulex SLI-4
  adapter.
- A libefc subdirectory: This subdirectory contains a library of
  common routines. Of major import is a number of routines that
  implement a FC Discovery engine for target mode.
- An efct subdirectory: This subdirectory contains the efct target
  mode device driver. The driver utilizes the above librarys and
  plugs into the SCSI LIO interfaces. The driver is SCSI only at
  this time.

The patches populate the libraries and device driver and can only
be compiled as a complete set.

This driver is completely independent from the lpfc device driver
and there is no overlap on PCI ID's.

The patches have been cut against the 5.5/scsi-queue branch.

Thank you to those that have contributed to the driver in the past.

Review comments welcome!
