ses device over T-SGPIO

The short story is: SGPIO sucks. It doesn't detect drive presence, much
less provide physical path information. The only thing you can do with it
is control the fault LEDs. But doing that usefully requires you to have
some extra source of information about what drives are installed in what
slots. Basically, you need to track that kind of information offline.
sesutil ought to be able to control the LEDs, at least, but I've never
personally used it with SGPIO.
