The ARMv8 architecture says that in the absence of FEAT_PMUv3, all the PMU-related register generate an UNDEF. Let's make sure that all our PMU handers catch this case by hooking into check_pmu_access_disabled(), and add checks in a couple of other places. Note that we still cannot deliver an exception into the guest as the offending cases are already caught by the RAZ/WI handling. But this puts us one step away to architectural compliance.
