Currently the rkisp1 pipeline handler only registers controls that are
related to the IPA. This patch prepares the rkisp1 pipeline-handler to
register camera controls which are not related to the IPA.

Hence, introduce a additional ControlInfoMap for IPA controls. These
controls will be merged together with the controls in the pipeline
handler (introduced subsequently) as part of updateControls() and
together will be registered during the registration of the camera.
This is similar to what IPU3 pipeline handler handles its controls.
