v0.3.2-patch1: Fix hard powerdown bug with pcUtil.
When triggering a power down via the power button, the handling of the shutdown request flag in the PMIC would incorrectly send a shutdown command back to the PMIC, causing the camera to hard powerdown. This would prevent the hwclock from getting a chance to save any changes, and can also lead to disc corruption.
