So far the mali-c55 pipeline has only supported cropping without using the scaling functionalities. Now that the kernel has gained support for the scaling operations, make the libcamera pipeline use it by combining it with a first cropping step to align the input and output images FOV ratio, and then scale to the desired output size.
