crypto: add rocksoft 64b crc guard tag framework
Hardware specific features may be able to calculate a crc64, so provide a framework for drivers to register their implementation. If nothing is registered, fallback to the generic table lookup implementation. The implementation is modeled after the crct10dif equivalent.
