[SCSI] lpfc 8.3.19: Add SLI4 FC Discovery support

Add SLI4 FC Discovery support

- Replace READ_LA and READ_LA64 with READ_TOPOLOGY mailbox command.
- Converted the old READ_LA structure to use bf_set/get instead of bit fields.
- Rename HBA_FCOE_SUPPORT flag to HBA_FCOE_MODE. Flag now indicates function
  is running as SLI-4 FC or FCoE port. Make sure flag reset each time
  READ_REV completed as it can dynamically change.
- Removed BDE union in the READ_TOPOLOGY mailbox command and added a define to
  define the ALPA MAP SIZE. Added FC Code for async events.
- Added code to support new 16G link speed.
- Define new set of values to keep track of valid user settable link speeds.
- Used new link speed definitions to define link speed max and bitmap.
- Redefined FDMI Port sppeds to be hax values and added the 16G value.
- Added new CQE trailer code for FC Events.
- Add lpfc_issue_init_vfi and lpfc_init_vfi_cmpl routines.
- Replace many calls to the initial_flogi routine with lpfc_issue_init_vfi.
- Add vp and vpi fields to the INIT_VFI mailbox command.
- Addapt lpfc_hba_init_link routine for SLI4 use.
- Use lpfc_hba_init_link call from lpfc_sli4_hba_setup.
- Add a check for FC mode to register the FCFI before init link.
- Convert lpfc_sli4_init_vpi to be called without a vpi (get it from vport).
