kvm_stat: Add kvm_exit reasons for aarch64

This patch defines the list of kvm_exit reasons for aarch64. This list is
based on the Exception Class (EC) field of HSR register. With this patch
users can trace the execution of guest VMs better. A sample output from
command "kvm_stat -1 -t" is shown as the following:
<...>
kvm_exit(WATCHPT_HYP)          0         0
kvm_exit(WFI)               9422      9361

NOTE: This patch requires TRACE_EVENT(kvm_exit) to include exit_reason
field in TP_ARGS. A patch to upstream kernel has been submitted.
