[PATCH 03/12] x86/rdt: Add rdt common/cqm compile option

Add a compile option INTEL_RDT which enables common code for all
RDT(Resource director technology) and a specific INTEL_RDT_M which
enables code for RDT monitoring. CQM(cache quality monitoring) and
mbm(memory b/w monitoring) are part of Intel RDT monitoring.
