sparc64: Add a basic conflict engine in preparation for multi-counter support. The hardware counter ->event_base state records and encoding of the "struct perf_event_map" entry used for the event. We use this to make sure that when we have more than 1 event, both can be scheduled into the hardware at the same time. As usual, structure of code is largely cribbed from powerpc.
