[SCSI] lpfc 8.3.20: Implement new SLI4 init procedures based on if_type

Implement new SLI4 init procedures based on if_type:

- Add structure changes for new SLIPORT registers and BAR changes.
- Update register names to be consistent with inteface spec terms.
- Added union to encapsulate Hardward error registers.
- Rework lpfc_sli4_post_status_check() around SLI-4's SLI_INTF type
- Removed the lpfc_sli4_fw_cfg_check routine
- Segmented driver logic to include evaluation of the if_type to
  engage different behaviors.
