perf/x86: Add Sandy Bridge constraints for CYCLE_ACTIVITY.*
Add CYCLE_ACTIVITY.CYCLES_NO_DISPATCH/CYCLES_L1D_PENDING constraints. These recently documented events have restrictions to counter 0-3 and counter 2 respectively. The perf scheduler needs to know that to schedule them correctly. IvyBridge already has the necessary constraints.
