[SCSI] lpfc 8.3.24: Extended hardware support and support dump images

Browse Source 
Extended hardware support and support dump images:
- Make the size to be MAILBOX_SYSFS_MAX (4096) so that it allows the maximum
  sysfs binary access interface possible.
- Add ids and model names for new hardware
- Add capability of inducing SLI4 firmware dump obj file
