[PATCH v3 12/14] media: imx-csi: Move crop/compose reset after filling default mbus fields

[Steve Longerbeam]

If caller passes un-initialized field type V4L2_FIELD_ANY to CSI
sink pad, the reset CSI crop window would not be correct, because
the crop window depends on a valid input field type. To fix move
the reset of crop and compose windows to after the call to
imx_media_fill_default_mbus_fields().
