[SCSI] lpfc 8.3.0 : Added 3 small features and improve PCI EEH support

- Added FC_REG_VPORTRSCN_EVENT to lpfc_nl.h

- Added code to provide option ROM version from HBA and via sysfs

- Added support for HPS bit in config port mailbox command to tell HBA
  that host group pointers are in host memory.

- Bugfix for Extended Error Handling (EEH) support on IBM PowerPC P6
  platform with MSI enabled
