powerpc/perf: Update Power PMU cache_events to u64 type
Events of type PERF_TYPE_HW_CACHE was described for Power PMU as: int (*cache_events)[type][op][result]; where type, op, result values unpacked from the event attribute config value is used to generate the raw event code at runtime. So far the event code values which used to create these cache-related events were within 32 bit and `int` type worked. In power10, some of the event codes are of 64-bit value and hence update the Power PMU cache_events to `u64` type in `power_pmu` struct. Also propagate this change to existing all PMU driver code paths which are using ppmu->cache_events.
