media: atomisp: Fix binning check in atomisp_set_crop()

The fmt / size passed to atomisp_set_crop() includes padding,
so the binning check should be against 1/2 of the native rect.
of the sensor, rather then 1/2 of the active rect.

This fixes binning not being used when using e.g. 800x600 on
a 1600x1200 sensor leading to a very small field of view.
