x86/intel_rdt: Make schemata file parsers resource specific

The schemata files are the user space interface to update resource
controls. The parser is hardwired to support only cache resources, which do
not fit the requirements of memory resources.

Add a function pointer for a parser to the struct rdt_resource and switch
the cache parsing over.
