media: imx335: Support 2x2 binning
commit 8a2451b upstream. Introduce 2x2 binning mode (1312x972@60fps). Since there are multiple modes now, use v4l2_find_nearest_size() to select the appropriate mode in .set_fmt(). For 2x2 binning the minimum shutter value supported is 17 instead of 9. This effects the maximum allowed exposure time, and if not enforced then the sensor produces very dark frames when the minimum shutter limit is violated. Lastly, update the crop size reported to the userspace. When trying 2x2 binning with the datasheet suggested pixel array size (i.e. 2592 / 2 => 1296), on some platforms (Raspberry Pi 5) artefacts are introduced on the right edge of the output image. Instead, using a higher width of 1312 works fine on all platforms.
