scsi: lpfc: SLI path split: Refactor base ELS paths and the FLOGI path

The patch refactors the general ELS handling paths to migrate to SLI-4
structures or common element abstractions. The fabric login paths are
revised as part of this patch:

 - New generic lpfc_sli_prep_els_req_rsp jump table routine

 - Introduce ls_rjt_error_be and ulp_bde64_le unions to correct legacy
   endianness assignments

 - Conversion away from using SLI-3 iocb structures to set/access fields in
   common routines. Use the new generic get/set routines that were added.
   This move changes code from indirect structure references to using local
   variables with the generic routines.

 - Refactor routines when setting non-generic fields, to have both SLI3 and
   SLI4 specific sections. This replaces the set-as-SLI3 then translate to
   SLI4 behavior of the past.

 - Clean up poor indentation on some of the ELS paths
