MIPS: KVM: Clean up kvm_exit trace event
Clean up the MIPS kvm_exit trace event so that the exit reasons are
specified in a trace friendly way (via __print_symbolic), and so that
the exit reasons that derive straight from Cause.ExcCode values map
directly, allowing a single trace_kvm_exit() call to replace a bunch of
individual ones.
