Other than these few raw vs row mistypes the patch is fine for me. My Reviewed-by tag holds.

The previously added modes 3264x2448 & 1632x1224 are actually configuring the sensor for BGGR mode, this is an issue since the mode that is exposed through V4L incorrectly is set as GRBG. This patch fixes the issue by moving the output crop window of internal sensor ISP uses by one row, which means that the Bayer pattern of the output is changed.
