V4L/DVB (12526): ov772x: do not use scaling for cropping
OV772x sensors cannot crop, they only support two fixed formats: VGA and QVGA. We should not change the format when requested to crop, only S_FMT can do this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
