[SCSI] bfa: Brocade-1860 Fabric Adapter 16Gbs support and flash controller fixes.
- Added support for 16Gbps. - Added logic to flush pending mailbox command queue when IOC is disabled. - Fix to Halt the flash controller during fw initialization - since when asic blck is programmed flash controller's continuous access blocks f/w access to flash. - Added new asic based card types and modified IOC get card model routine. - Added PLL init fix to do LPU reset every time we do a memory initialization, since not doing so will cause LPU to be uninitialized during driver load. - Added fix to Halt flash controller before PLL initialization.
