sparc64: Fix Niagara2 perf event handling.
[ Upstream commit e04ed38d4e0cd32141f723560efcc8252b0241e2 ]
For chips like Niagara2 that have true overflow indications
in the %pcr (which we don't actually need and don't use)
the interrupt signal persists until the overflow bits are
cleared by an explicit %pcr write.
