[PATCH 2/7] KVM: arm64: PMU: Use reset_pmu_reg() for PMUSERENR_EL0 and PMCCFILTR_EL0

The default reset function for PMU registers (reset_pmu_reg())
now simply clears a specified register. Use that function for
PMUSERENR_EL0 and PMCCFILTR_EL0, since those registers should
simply be cleared on vCPU reset.
No functional change intended.
