Put s5h1411 into low power mode at end of attach() call
From: Devin Heitmueller <devin.heitmueller@gmail.com>
Place the s5h1411 into low power mode until first use (to handle the case where
the user plugs in the device and then doesn't use it for a while). On the
Pinnacle 801e, this brings the power usage from 126ma down to 82ma.
