libcamera: ipu3: imgu: Filter resolutions < IF_CROP_MAX

As reported in https://bugs.libcamera.org/show_bug.cgi?id=32
allowing resolutions < IF_CROP_MAX leads to a not manageable number
configurations to be tested, slowing down the ImgU pipe configuration
to a point which is not acceptable for production devices.

Filter all resolutions < IF_CROP_MAX to maintain the run-time complexity
acceptable and remove the safety check that was meant to avoid overflows
when computing the IF rectangle sizes.
