f917810061 Removed RocketCoreParameters from use. 
- The nbdache (among others?) use CoreParameters, which has nothing to do with RetireWidth requirements.
   - This conflicts with other cores which uses nbdcache.
   - RocketCoreParameters may be unneccessary, and the require() check can be moved deeper into Rocket.

868e747656 Factored out Rocket specifics from CoreParameters 
- Added new RocketCoreParameters
   - Other cores using Rocket as a library will no longer conflict against
      Rocket's requires().
