x86/intel_rdt/cqm: Add RDT monitoring initialization

Add common data structures for RDT resource monitoring and perform RDT
monitoring related data structure initializations which include setting
up the RMID(Resource monitoring ID) lists and event list which the
resource supports.

[ tony: some cleanup to make adding MBM easier later, remove "cqm" from
  	some names, make some data structure local to intel_rdt_monitor.c
  	static. Add copyright header]

[ tglx: Made it readable ]
