Will Deacon c318d7b4db ARM: perf: hook up perf_sample_event_took around pmu irq handling ...

commit 5f5092e72c upstream.

Since we indirect all of our PMU IRQ handling through a dispatcher, it's
trivial to hook up perf_sample_event_took to prevent applications such
as oprofile from generating interrupt storms due to an unrealisticly
low sample period.
