[PATCH v3 09/20] media: i2c: imx219: Use active crop rectangle to configure registers

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

Configure the crop-related registers from the values stored in the
active crop rectangle instead of the mode structure. This removes usage
of the mode from the imx219_set_framefmt(). No functional change is
intended.
