[SCSI] lpfc 8.3.17: SLI Additions and Fixes

- Added driver support for management application to pass down two security
  specific mailbox commands (MBX_SECURITY_MGMT and MBX_AUTH_PORT)
- Added driver support for handling FIPS zeroization trap of host ERATT ER8,
  performing selective reset and bringing the device up.
- Added code to detect INIT_LINK mailbox command completion returning status
  MBXERR_SEC_NO_PERMISSION.
- Increased the wait timeout on host status register HS_FFRDY and HS_MBRDY
  being set.
- Remove the port offline code from the Heartbeat TMO handler.
