When color space V4L2_COLORSPACE_JPEG is requested the ISP incorrectly
sets the output quantization to V4L2_QUANTIZATION_LIM_RANGE. Fix that by
applying the default quantization for the requested color space.
Fixes: c1ec5efba080 ("media: rkisp1: Allow setting all color space fields on ISP source pad")
