ipa: raspberrypi: Generalise the ALSC algorithm
Remove any hard-coded assumptions about the target hardware platform from the ALSC 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. The ALSC calculations use run-time allocated arrays/vectors on every frame. Allocating these might add a non-trivial run-time penalty. Replace these dynamic allocations with a set of reusable pre-allocated vectors during the init phase.
