Consistency. Print message 1) only if secure rx51 smc instruction is called or 2) print message always (also if smc is not called). With that patch message is printed (enabled/disabled) only if device is rx51 and device type is HS.
For information it is also good to know that in qemu that special secure smc instruction was not called.
