v0.3.2-patch2: Fix enable and disable of zebra stripes.

The build of cam-pipeline that got released in v0.3.2-patch1 had a bug due to a partially implemented API call to set the zebra stripes by another method.

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.
