[media] atmel-isi: move configure_geometry() to start_streaming() 

As in set_fmt() function we only need to know which format is been set,
we don't need to access the ISI hardware in this moment.

So move the configure_geometry(), which access the ISI hardware, to
start_streaming() will make code more consistent and simpler.
