ipu3: cio2: Change sensor size selection policy
The current implementation of getSensorFormat() prioritizes sensor sizes that match the output size FOV ratio. Modify the frame size selection procedure to prioritize resolutions with the same FOV as the sensor's native one, to avoid cropping in the sensor pixel array. For example: - on a Soraka device equipped with ov13858 as back sensor, with a native resolution of 4224x3136 (4:3), when requested to select the sensor output size to produce 1080p (16:9) a frame size of 2112x1188 (16:9) is selected causing the ImgU configuration procedure to fail. If a resolution with the same FOV as the sensor's native size, such as 2112x1568 (4:3), is selected the pipeline works correctly.
