libcamera: pipeline: raspberrypi: Start IPA when starting camera
The IPA is meant to be started when starting the camera, and stopped when stopping it. It was so far started early in order to handle the IPAInterface::processEvent() call related to lens shading table allocation before IPAInterface::configure() to pass the table to the IPA. Now that the lens shading table is passed through configure(), starting the IPA early isn't needed anymore.
