This makes the BL and FW images distinct devices with unique serial numbers. Windows (and maybe Mac) remembers the device descriptors and the associated drivers based on this serial number. Providing unique serial numbers for the BL and FW images allows us to provide different sets of descriptors for the BL and FW images without confusing these OSes. BL version number is now also bumped to reflect the new serial number generation algorithm.
