For example on the ov2680 which has a native resolution of 1616x1216 the max active resolution of 1600x1200 leaves 16x16 for padding which meets the worst-case minimum padding requirement of 14x14 on BYT. But after binning we are left with an native area of 808x608 and an active area of 800x600. This leaves 8x8 for padding which is not enough. So on BYT 800x600 is not a valid resolution (it could be made by lots of cropping without binning but then the remaining field of view is no good). Modify atomisp_enum_framesizes_crop() to check the resolution + padding fits in the native rectangle, removing 800x600 from the list of valid modes on BYT.
