[SCSI] qla2xxx: Add Flash Descriptor Table layout support.
The Flash Descriptor Table (FDT) present on many recent HBAs
encodes flash accessing characteristics of the flash-part used on
the HBA. Use this information during flash manipulation (writes)
rather than using specific hard-coded values based on queried
manufacturer and device IDs.
