Allow the sensor to report the per-resolution frame interval. It should be noticed that, despite the ov2680 datasheet says that, for resolutions <= 1280x720, the sensor supports 60fps, the data at ov2680.h tells otherwise, limiting it to 30fps. Not sure yet if this is a limitation of atomisp or if it is just because the tables are incorrect.
