This is the second version of the series that adds support for the
Exynos4x12 device to the s5p_jpeg driver along with accompanying
fixes. It contains following improvements
(Hans, Sylwester thanks for the review):

- moved adjusting chroma subsampling control value from s_ctrl
  to try_ctrl callback and switched from using v4l2_s_ctrl to
  v4l2_ctrl_s_ctrl
- avoided big switch statement in favour of lookup tables
  for adjusting capture queue fourcc during decoding phase
- avoided unnecessary displacement of clk_get call in the probe function
- renamed decoded_subsampling_to_v4l2 to s5p_jpeg_to_user_subsampling
- added freeing ctrl_handler when v4l2_ctrl_handler_setup fails
- calling s5p_jpeg_runtime_suspend and s5p_jpeg_runtime_resume
  only when pm_runtime_suspended returns false

Thanks,
Jacek Anaszewski
