USB: serial gadget: descriptor cleanup
Bugfix some serial gadget descriptors: - Stop mangling the low bits (controller type ID) of bcdDevice; just use the high bits for a driver revision code. - Serial numbers that aren't specific to individual devices are useless; stop reporting "0" for this. - Since it's not part of a CDC-conformant function, the "bulk only" configuration shouldn't be using "CDC Data" as its interface class. Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).
