ipa: raspberrypi: Generalise the autofocus algorithm
Remove any hard-coded assumptions about the target hardware platform from the autofocus algorithm. Instead, use the "target" string provided by the camera tuning config and generalised statistics structures to determing parameters such as grid and region sizes. Additionally, PDAF statistics are represented by a generalised region statistics structure to be device agnostic. These changes also require the autofocus algorithm to initialise region weights on the first frame's prepare()/process() call rather than during initialisation.
