x86/intel_rdt: Move CBM specific data into a struct
Memory bandwidth allocation requires different information than cache
allocation.
To avoid a lump of data in struct rdt_resource, move all cache related
information into a seperate structure and add that to struct rdt_resource.
Sanitize the data types while at it.
