The default reset function for PMU registers (defined by PMU_SYS_REG)
now simply clears a specified register. Use the default one for
PMUSERENR_EL0 and PMCCFILTR_EL0, as KVM currently clears those
registers on vCPU reset (NOTE: All non-RES0 fields of those
registers have UNKNOWN reset values, and the same fields of
their AArch32 registers have 0 reset values).
No functional change intended.
