Report the native sensor size (pixel array), the crop bounds (readable pixel array area) and the current and default analog crop rectangles. Currently all driver's mode use an analog crop rectangle of size [12, 4, 2600, 1952]. Instead of hardcoding the value in the operation implementation, ad an .analog_crop field to the sensor's mode definitions, to make sure that if any mode gets added, its crop rectangle will be defined as well. While at it re-sort the mode's field definition order to match the declaration order and initialize the crop rectangle in init_cfg().
