perf/x86/intel/cstate: Add C-state residency events for Knights Landing
Although KNL does support C1,C6,PC2,PC3,PC6 states, the patch only
supports C6,PC2,PC3,PC6, because there is no counter for C1.
C6 residency counter MSR on KNL has a different address than other
platforms which is handled as a new quirk flag.
