media: atomisp: Fix atomisp_try_fmt_cap() always returning YUV420 pixelformat
The atomisp_try_fmt() call in atomisp_try_fmt_cap() replaces the pixelformat passed by userspace with the sensors native pixelformat. Which always gets replaced by V4L2_PIX_FMT_YUV420 by atomisp_adjust_fmt() because raw sensor formats are not supported. This needs to be fixed so that userspace which does a try_fmt call before s_fmt does not end up always getting YUV420 even if it passed something else into the try_fmt call. To fix this restore the userspace requested pixelformat before the atomisp_adjust_fmt() call. atomisp_adjust_fmt() will replace this with V4L2_PIX_FMT_YUV420 in case an unsupported format is requested. Note this relies on the "media: atomisp: Refactor atomisp_adjust_fmt()" change, before that atomisp_adjust_fmt() would return -EINVAL for unsupported pixelformats.
