drivers/perf: hisi: Export hisi_uncore_pmu_isr()

Currently Uncore PMU framework assume one PMU device only have one
interrupt and will help register the interrupt handler. It cannot
support a PMU with multiple interrupt resources.  An uncore PMU may
have multiple interrupts that can share the same handler.  Export
hisi_uncore_pmu_isr() to allow drivers register the irq handler by
their own routine.
