[SCSI] lpfc 8.3.6 : Hardware related fixes and changes

Hardware related Fixes and Changes.
 - Added new Adapter IDs and update default Adapter names.
 - Added PCI read after EQarm doorbell PCI write to flush the write
   and avoid spurrious interrupts when in INTx mode.
 - Phase out use of ONLINE registers.
 - Fix for lost MSI interrupt
