KVM: arm64: Compute synthetic sysreg ESR for Apple PMUv3 traps
Apple M* CPUs provide an IMPDEF trap for PMUv3 sysregs, where ESR_EL2.EC
is a reserved value (0x3F) and a sysreg-like ISS is reported in
AFSR1_EL2.
Compute a synthetic ESR for these PMUv3 traps, giving the illusion of
something architectural to the rest of KVM.
