* Configure pmic to enter OFF-state instead of SLEEP-state ("RTC-only

* For details, see linux-omap mailing list May 2015 thread
* [PATCH] ARM: dts: am335x-bone* enable pmic-shutdown-controller
* In particular, messages:
* http://www.spinics.net/lists/linux-omap/msg118585.html
* http://www.spinics.net/lists/linux-omap/msg118615.html
*
* You can override this later with
* &tps { /delete-property/ ti,pmic-shutdown-controller; }
* if you want to use RTC-only mode and made sure you are not affected
* by the hardware problems. (Tip: double-check by performing a current
* measurement after shutdown: it should be less than 1 mA.)
