CAL has 4 pixel processing units but the units are not needed e.g. for metadata. As we could be capturing 4 pixel streams and 4 metadata streams, i.e. using 8 DMA contexts, we cannot assign a pixel processing unit to every DMA context. Instead we need to reserve a pixel processing unit only when needed. Add functions to reserve and release a pix proc unit, and use them in cal_ctx_prepare/unprepare. Note that for the time being we still always reserve a pix proc unit.
