[SCSI] lpfc 8.3.20: Implement the FC and SLI async event handlers

Browse Source 
Implement the FC and SLI async event handlers:

- Updated MQ_CREATE_EXT mailbox structure to include fc and SLI async events.
- Added the SLI trailer code.
- Split physical field into type and number to reflect latest SLI spec.
- Changed lpfc_acqe_fcoe to lpfc_acqe_fip to reflect latest Spec changes.
- Added lpfc_acqe_fc_la structure for FC link attention async events.
- Added lpfc_acqe_sli structure for sli async events.
- Added lpfc_sli4_async_fc_evt routine to handle fc la async events.
- Added lpfc_sli4_async_sli routine to handle sli async events.
- Moved LPFC_TRAILER_CODE_FC to be handled by its own handler function.
