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).
